I couldn't get the nv to do multihead either.  BTW, when I had probs 
with the nvidia driver and freezes, it was always when one of the GLX 
screensavers was activated.  (This was a pre-release fedora core 2 
problem, if I remember correctly.)

If that's the case for you, you might just settle for a single, non-GLX 
screen saver (rather than, say, random) to keep from locking up, then 
report your issues to:

	https://bugzilla.ubuntu.com

and maybe let one of the kernel guys ask you for tests for your 
particular hardware situation.

Good luck!
