I don't know what modes GRUB currently supports, but if it doesn't

needs to be fixed by adding more cruft to Xen.
I'm pretty sure that GRUB won;t set up all the nice vga gfx modes on
behalf of an OS, and even if it does you'd still need font data and
other smarts in the OS to make use of the hi-res mode. Extra patches to
GRUB are a pain because in my experience they are almost impossible to
get accepted upstream.
