IIRC, I had the same problem with a FC3 because of udev and no /dev/sd*
devices in the domain0.
You can either create the devices manually (cd /dev && MAKEDEV sda), or
use hda1, hda2 instead of sda1, sda2.

Yes, but xen probably needs those in order to find out the major and
minor information.
It would be nice if xen was changed to try some defaults for sd and hd,
though.
