I just realised that I am having the same problem with 2.6.22.7-85.fc7
... IF .... I start with init level 3 ( I append 3 at the kernel
parameters in grub ). Starting with init level 5 does not have the
problem.

Of course, when running 2.6.22.9-91.fc7, I still dont have the nvidia
binary module installed for that kernel yet, so I start it at run
level 3 ( also by appending 3 at the kernel parameters in grub ).

Can anyone shed some light ?
