So, where could be the Problem =?
Hmmh, so let's see, have you also selfcompiled XFree86 ? If yes, post your host.def. Otherwise, and seems now more likley to me, the problem lies in our kernel configuration.
As I said, the driver is perfectly working when I boot my Mandrake 8.0 on the same hardware, there I have also upgraded the Kernel myself to 2.4.8-ac7
