I also think its a grub2 problem maybe in combination with some "exotic" 
hardware configurations (let me guess, you are using fakeraid on hd0 and 
hd1 with hd2 being a plain disk?)
I'm encountering exactly the same issue, except that I *cannot* solve it 
by using (hd1,1) instead of the "real" (hd2,1).
I know that there is no mistake in my grub config, I'm using the same 
kernel with the same grub config to boot on bare metal, but as soon as I 
add multiboot and xen there are stange errors:
- when loading xen.gz like "(hd2,1)/boot/xen.gz" it does not work (error 
message same as Thomas: "need to load multiboot kernel first")
- when entering the grub shell and trying to autocomplete (using tab) to 
/boot/xen.gz the system reboots itself while doing so
- when loading xen.gz like "/xen.gz" (with a copy of xen.gz outside the 
boot dir) it loads xen, but then complains about no dom0 kernel being 
specified (this also persist when trying to take a copy of the vmlinuz 
outside of /boot to /)
This is my first Ubuntu *and* grub2 system, usually I'm running Gentoo 
and grub... thought things (especially updates) may get less time 
consuming using Ubuntu... lesson learned and back to Gentoo!

Best regards,
