Очень на то похоже -- тоже Lifebook, тоже Rage Mobility, 
тоже 2X, но 4M.

2.6.10-wks26-up-alt5, загрузил intel_agp, agpgart, mach64;
xorg-x11-6.8.2-alt7, прописал Load'ы dri, glx.

agpgart: Detected an Intel 440BX Chipset.
agpgart: Maximum main memory to use for agp memory: 96M
agpgart: AGP aperture is 64M @ 0xf8000000
[drm] Initialized mach64 1.0.0 20020904 on minor 0: ATI Technologies Inc Rage Mobility P/M AGP 2x

(--) ATI(0): 4096 kB of SGRAM (2:1) 32-bit detected (using 4095 kB).
(WW) ATI(0): DRI static buffer allocation failed -- need at least 4608 kB video memory
(II) ATI(0): Direct rendering disabled

Соответственно в 800x600x16 (брр, оно отмасштабировалось):

...но почему-то

life:~> glxinfo|grep ^direct

libGL error: reverting to (slow) indirect rendering

После sudo chown $USER /dev/dri/card0 поправилось;
FPS в glxgears поднялись со ~113 до ~140, правда, не знаю, 
на чём масштабирование выполняется (800x600 растянуто
на весь экран, лезть отключать лень).

(можно было дочитать это и прописать Section "DRI"...
http://dri.freedesktop.org/wiki/DriTroubleshooting)

С libGL вроде порядок:

libGL error:

В общем, по ссылкам в цитате всё сказано. :-)

Т.к. машинка и не предполагала, то отключаю заради памяти, 
но приятно, что в Xorg уже смержили найденный перед покупкой
ноута скорее из любопытства код для Mach64 DRI. :-)

PS: проверил ppracer.  Четыре с хвостиком FPS, ездит :)))
