Hmmm...maybe they recently changed something and started supporting it.
But I've already traded in my Nvidia card for a very nice fully

Yup. I was surfing the nVidia forums several months back when I was first
trying to set things up. At the time, there wasn't "official" support for
the Xen kernel, however, others had hacked up support. I was able to get
things working that way. Now a days, the nVidia driver is available via
yum. Sometimes it lags a few days behind the kernel release but usually
it's pretty quick to get in Livna. Then again, I'm not sure if this is the
"official" nVidia-sanctioned driver or still the third-party hack. For what
it's worth, it works...
Of course, the domU kernels don't work (directly) with the nvidia
driver. Not sure if anyone has had any success with video for domU
though. What's the word there?
domU's can't share the video card yet. Probably won't be able to at
least until you upgrade to a new cpu with the IO virtualization
extensions. But there is really too much state saved in a modern video
card to make virtualizing it very easy.
I don't necessarily want to share the video card between domUs or even with
the dom0. My preference would be to strip the dom0 side down to the bare
minimum running headless (other than virtual consoles), have one domU that's
used to provide my interface (using the video card), then the rest of the
domUs can be headless running whatever they need to that doesn't require
direct access to the video card.
