Yes.  It expects some new bochs vbe interface bits being present.  qemu 
doesn't provide them (yet), thus it simply doesn't work.

Oh, there is one noticable improvement (patch attached, cherry-picked 
from vgabios cvs).  vgabios can pick the lfb address from pci config 
space now.  This in turn allows us to kill the lfb mapping at hardcoded 
address 0xe0000000 (except for isapc).

cheers,
