[My second answer, now that I've looked at that code and understand
better where you're going with this ...]

Yes, I think this is all possible, and probably better than emulating
what the BIOS does.  Even better would be if you could get those 1024
bytes down to 512 bytes (and thus fit it in a boot sector).  Then no
changes to existing hypervisors would be needed at all, and it would
run on baremetal.
