   Hi,

 I have a similar issue: I am testing Lucid on a PC (amd64) )with two nVidia cards (one 9600GT with two screens attached, and ont GTX295 for CUDA computing). Kubuntu (beta2) installs fine, and works all right with the nouveau driver.
 Since I need CUDA, I installed nvidia-current (195.36.15), and after reboot the system hard-freezes right around the time the graphics should appear - I assume that's exactly when the nvidia module is launched, though I do not have a log to show immediately.

  If I remove any of the cards, everything works all right (still with
the nvidia 195.36.15 driver).

  Note that this is from a Lucid beta2 clean install, after all
available updates have been installed (-generic or -server kernel makes
no difference). The most annoying part is that when this happens, for
some reason I am not even able to boot in recovery mode, the PC also
crashes... The only solution is to reboot with only one card.

  There are a few messages related to this in the nVidia forums, although no working solution has been reported. See for example:
http://www.nvnews.net/vbulletin/showthread.php?t=149415

  I tried disabling the VGA Arbiter in the kernel as  suggested, but
apparently the kernel VGA_ARB option is automagically turned backed to
'yes', due to some kernel config dependency I have not yet found...
