I wonder if you replaced a non-Xen kernel with a Xen one, rather than
installing it as an additional kernel?
I tried with several different kernels but get the same result.

Perhaps your map file doesn't really show what's considered hd0
Try issuing root (hd1,0), and see what difference it makes. You can
just type in (hd and hit the tab key, you'll get auto-complete
from what's available.
If something considers the order of the drives to be different,
they'llcount the other way around.
grub> root (<TAB>
grub> root (hd0,
Entering 0 gives me the "Filesystem type unknown..." error, entering
any other number gives me a "disk not found" error. I tried root
(hd1,0) but this doesn't work either.
If I try the auto completion with a kernel command, I get this:
grub> kernel /vmlin<TAB>
Error 17: Cannot mount selected partition.
I am guessing this is because the root command fails.
