added a couple of new bits of support from bug 170293. while i was editing the doc anyway, also went through and revamped several other sections, including adding new info on the latest ati cards (no support for R600/HD 2000 series), other xorg driver support updates, removed 2.4 kernel stuff, removed x11-drm per previous updates to the hardware accel guide, and condensed install instructions

19 This FAQ should help users avoid some common installation and configuration
20 issues related to DRI and X11 for ATI boards.

36 <p>
37 Many ATI boards (but not all) are supported by <uri
38 link="http://www.freedesktop.org/Software/xorg">xorg-x11</uri>, at least for the
39 2D accelerated features. The 3D support is provided either by xorg-x11, or by
40 ATI's <uri
41 link="http://mirror.ati.com/support/drivers/linux/radeon-linux.html">closed
42 source drivers</uri>.

84 The x1000 series cards (x1300 and higher) cannot use the free xorg drivers; they
85 are limited to the unaccelerated 2D vesa driver. Use the proprietary
86 <c>ati-drivers</c> package if you want hardware-accelerated 2D/3D graphics.
87 </p>
88
89 <impo>
90 The newest Radeon HD 2000 series cards are completely unsupported in Linux.
91 There are no drivers from either xorg or ATI. It's probably best to hold off
92 buying these cards until there's some kind of support in Linux. ;)

99 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
100 </title>
101 <body>
102
103 <p>
104 The board's multimedia features are supported by <uri
105 link="http://gatos.sf.net">the GATOS project</uri>. These drivers will be
106 merged into the xorg tree shortly.

112 <title>I'm not using an x86-based architecture. What are my options?</title>
113 <body>
114
115 <p>
116 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
117 However, ATI's closed source drivers are not supported on the PPC or Alpha, so
118 you cannot use the 3D features of the R300 Graphics Processing Unit (GPU). If
119 you have such a board and want it supported by X11, contact <uri
120 link="http://www.ati.com">ATI</uri> and ask them to release the specifications
121 for your system's GPU. The closed source driver for the AMD64 was released, so
122 AMD64 users can now enjoy the same features as x86 users.
123 </p>
124
125 <impo>
126 To enable agpgart support for certain AMD64 chip sets, you have to disable
127 support for the K8 IOMMU.

133 <title>I have a laptop. Is my ATI Mobility model supported?</title>
134 <body>
135
136 <p>
137 It should be, but you may have a configuration issue due to the OEM PCI id that
138 such chips may have. In most cases, you may have to write the configuration
139 file yourself or use the <c>xorgconfig</c> utility.

151
152 <p>
153 There are two ways of getting drivers for your ATI card:
154 </p>
155
156 <ul>
157 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
158 <li>
159 The <c>ati-drivers</c> ebuild provides the ATI closed source X drivers and
160 kernel modules
161 </li>
162 </ul>
163
164 <p>
165 If you want to use ATI's <e>internal</e> agpgart support instead of the Linux
166 kernel one, the agpgart driver and the chip set specific driver (in your kernel
167 configuration) must be built as modules or not at all.
168 </p>
169
170 <note>
171 Please read the <uri link="/doc/en/dri-howto.xml">Hardware Acceleration
172 Guide</uri> for more information on installing drivers for your ATI graphics
173 card.

178 <section>
179 <title>Configuration</title>
180 <body>
181
182 <p>
183 The use of <c>xorgcfg</c> or <c>xorgconfig</c> to generate the
184 <path>xorg.conf</path> configuration file is suggested. Alternatively, you may
185 use the Xorg auto configuration option:
186 </p>
187
188 <pre caption="Autoconfiguring X">
189 # <i>X -configure</i>
190 </pre>
191
192 <p>
193 For more information on how to get a basic <c>xorg.conf</c> configuration file,
194 please refer to the <uri link="/doc/en/xorg-config.xml">Gentoo X Server
195 HowTo</uri>.
196 </p>
197
198 <note>
199 You can use <c>aticonfig</c> if you have installed the <c>ati-drivers</c>
200 package.
201 </note>
202
203 <impo>
204 PPC users could use the <c>Xorgautoconfig</c> stand-alone configuration tool by
205 emerging the <c>Xorgautoconfig</c> ebuild, but isn't required.

213
214 <p>
215 Once X is installed, configured, and running, it can use the ATI OpenGL
216 libraries:
