I'm still debugging issues with more complex clients booted by grub2. 
For example, grub invaders "boots" correctly, but it doesn't require any
setup by multiboot. OpenSolaris (using multiboot) and Linux (using the
linux loading routine) both fail for me right now.

One issue could be that grub2's multiboot implementation is still
unfinished (you can try that by trying to boot your xen image on a
system with normal bios and a i386-pc version of grub2), the other, that
there are bugs in the boot loader routines in cbgrub2. (definitely the
case for linux)
