X.org の ATi Radeon X800 ドライバは ATi から提供されています．

手順通りにインストールしたはいいものの，なぜか起動しません．

/var/log/Xorg.0.log の最後には次のように書いてありました．

(EE) No devices detected.

ありゃー，ちゃんと RADEON X800 (R423 5548) があるじゃないの，と思いつつ．lspci を実行すると...

0000:04:00.0 VGA compatible controller: ATI Technologies Inc: Unknown device 554f
0000:04:00.1 Display controller: ATI Technologies Inc: Unknown device 556f

あれ，デバイス ID が違う? ああ，そういえば AGP 版と PCI Express 版のチップって別物でしたっけ．

さて，どうしましょう... 最終的には vesa になるんでしょうか．

デバイス ID を誤魔化す方法を考えてみますか．

ありました．というわけで xorg.conf を編集します．

Section "Device"
    Identifier  "ATI RADEON X800"
    Driver      "fglrx"
    ChipID      0x5548
    Screen      0
EndSection

Section "Device"
    Identifier  "ATI RADEON X800 - Secondary"
    Driver      "fglrx"
    ChipID      0x5568
    Screen      1
EndSection

強調箇所が追加箇所です．こうやってデバイス ID を誤魔化して X を起動してみます．

... 残念．起動しません．しかし X のログには以下の内容が残ってました．

(WW) fglrx: No matching Device section for instance (BusID PCI:4:0:1) found
(**) ChipID override: 0x5548
(**) Chipset RADEON X800 (R423 5548) found

ちゃんと誤魔化せてます．ということは他の部分で死んでいるのでしょう．X のログをもう少し先まで読んでみます．

ぎゃぁ，なんだこれは!

見当はついてます．おそらく X.org のドライバに同梱されていたカーネルの dri ドライバ(fglrx.ko)が必要なんでしょう．

modprobe fglrx でロードしようとすると，X.org 側のドライバ同様，"No such device" エラーが出てロードされないので放置してましたが... こちらもデバイス ID を誤魔化してロードする必要があるようです．
