Via Nano X2 Support, cont'd?

Hi!

Recently got a Via VE-900 board. It has a via nano x2 chip on it, and suggests that it has Intel-compatible virtualization extensions. Has anyone worked with this board yet? I thought it would be nice to have a lower-powered, nearly silent Xen machine sitting on my desk.

I've got it booting into Xen 4.1.2 and running PV dom0's, but I'm not able to load any HVM domains. I posted this question first on Xen-users, and I was asked if I was able to get KVM or VirtualBox working-- I've tried KVM and managed to get it booting into a Linux livecd and a Windows installer.

Here's the /proc/cpuinfo (of one of the cores):
