Great !
Plase, send me some infos about the HW ! That is:
- tarball of /proc/device-tree
- lspci -vv ourput (as root)
- dmesg output
Thanks !

Ok, try this one: http://penguinppc.org/~daniels/README, and for now,
use it with NoAccel until I'm done ironing out some problems with Mark.
So far, the above version (based on XFree CVS "nv" driver) appear to
work fine on GeForce4MX based macs and on a GeForceIIMX I have in my
dual G4, though it doesn't quite work with the eMac's one yet.

Sleep will not work for some time at least :( Segher and I need to
complete an Open Firmware emulator in order to soft-boot the video
chip on wakeup from sleep.

It's probably a dual speed machine, I suspect you can switch it's speed
via the cpufreq interface. Those machines usually boot at low speed.
Check the actual speed by looking at BogoMips ;)
