Oh, bugger.  I hadn't gotten to testing this yet...  :-(

Anyone have any idea when/if the NVIDIA drivers will work with a pv_ops 
dom0?

What if I manage to get VGA passthrough to a domU?  Will the NVIDIA 
drivers work there?

How about alternatives video cards...  The only feature of the NVIDIA 
driver that we really required was enabling a second monitor, which didn't 
work with the opensource 'nv' driver.  Would an ATI card fare better here?
