I'll give that a shot tonight, thanks for the suggestion. I really
appreciate your efforts and if that doesn't help, I'll see if anyone
on the ivtv-devel list is into Xen too. I wish I had the kernel
programming expertise myself. But at least the drivers work well in
dom0.

Stupid question, but is there any way to tell Xen to allocate a domU
contiguously? Or is that just not the Xen way, so to speak?
