Hmm, interesting. I would have hoped such thing would exist, but I
can't see how it could work, since the code affected by
CONFIG_VIDEO_SELECT (which is what in non-guest Linux deals with the
vga= option) doesn't even exist in XenLinux. Further more, since XEN is
a multiboot image, it would require infrastructure to switch back to
real mode for issuing the necessary INT10-s in the guest kernel, which I
think is neither very desirable nor existing.

So I must be missing something, but I'd need a pointer at where I would
have to look for the alternative code.
