Not true.  The driver I deliver to Nevada/OpenSolaris is supposed to 
work all
the way back to S10 GA.  AFAIK, I've only broken S10 support
once (a Makefile goof that won't happen again).  This driver also
has xVM support enabled conditionally, so it should "just work"
if/when xVM graphics support is back ported to S10.

As of this writing, none of the graphics drivers at the NVIDIA download
site have xVM support.  xVM support is only available in the drivers
delivered by Sun.  If you load a driver directly from NVIDIA and
boot dom0, assume bad things will happen.

Unless you hit this problem:

  6661292 nv_devmap errors running Boing screen saver

the worst case hit I've seen running xVM dom0 is 50%, not a couple
of orders of magnitude.  This bug is fixed in the 169.11 driver
delivered to b83.

If Attila can privately send me the output of 
/usr/bin/nvidia-SunOS-bug-report.sh
after glxgears shows single digit frame rates, I will investigate.
