Don't know I currently use:
  NVIDIA-Linux-x86_64-285.05.09: 4.2.0 NVIDIA 290.10

AFAIK ubuntu uses the latest  NV driver .. hmm

I use kubuntu 11.10 and 10.* w/o problems .. hmm.
With and w/o compositor (effects, transparency).

Sure, could be some gnome thing and it's compositor,
but last test on CentOS (a while back) and Debian test went ok.

Never had this black in/out 'experience'.
NV 8400GS ? Hmm .. tests on an old MBP w/ an NV 8xxx worked fine as well.

Don't know the state of those drivers .. well.

Just know that Mesa also lacks of pbuffer support,
last time I checked (2 weeks?).
