It's certainly more of a pain to make the mode switch, but not impossible by
any means.

Oh yes, we definitely want the mode-switching code in Xen. No doubt about
that. The question is whether we pull in the EDD/EDID stuff as well. The
fact that the data format is BIOS-defined does make the current approach
plausible if not particularly tasteful architecturally speaking (but what
BIOS stuff is? :-).
