So grub in Ubuntu 10.04 uses _Linux_ device naming in the bootloader
configuration? That seems like an awfully big break with tradition.

Do you know how grub2 tries to interpret this, perhaps using a
device.map type file in /boot/grub? Or perhaps it is simply a bug in
10.04 beta?

sda isn't really a valid name for a modern PV domU kernel anyway. It
should be xvda. Looks like you need to do some additional tailoring to
convert your HVM Ubuntu domain into a PV one.

Ian.
