I've installed a fresh Gentoo box and wanted to give pv_ops a try.

After installing Xen 4.1 and fetching the latest 2.6.38 kernel, I've
compiled the kernel and tried to boot it. On bare metal (no xen), it
runs perfectly, but if I try to chainboot via xen, the machine boots
fine (can connect to it via SSH and dmesg shows xen is working) but on
the machine itself I have no image on the display. The video card is a
nVIDIA 8500GT, for reference.

After hitting <enter> in grub, I can see the XEN hypervisor booting
(messages prefixed with (XEN) ) but when it gets to the actual dom0
kernel, the image stays blank forever.

XEN hypervisor log: http://pastebin.com/AYbP2VDT
dom0 log: http://pastebin.com/dJFRfyYn
dom0 kernel config: http://pastebin.com/DcF3tfS0

As you can see, there's no kinky stuff involved, such as framebuffer
or special drivers...

Any thoughts/hints?
