  I was having similar problems with the nvidia driver on my
6.4-PRERELEASE machine.

  The solution was to remove agp and drm related drivers from
the kernel configuration and setting:

hw.nvidia.registry.EnableAGPFW=1
hw.nvidia.registry.EnableAGPSBA=1

  In my sysctl.conf, and also setting:

    Option         "NvAGP" "3"

  In my xorg.conf in the Screen section...

  The concrete problem -- not related with GL failures -- was
system freezing with /sysctl -a/ command on terminal emulators 
from X server.

  I hope it would help.
