My guess it that for some reason the xen drivers are not being loaded
for this kernel as they are in the ec2 version of the kernel. Check
the config for this kernel that is stored in /boot. You should be able
to either install another kernel package that was properly configured
or use apt-get source on the linux image and add in the Xen-related
drivers.

Hope that helps.

Thanks,
Todd
