So I tried getting the pvops kernel working and it works fine as a
standard Linux kernel but when I try to run it on top of Xen once I get
to Linux I don't have any keyboard input. I'm using the grub conf on the
pvops page so that part of the config should be correct. I'm going to
try to update to the latest version of xen-unstable and of the pvops
tree to see if that fixes anything.
