You could probably just add the pci ids to sisfb; The xgi chips were
just rebadged sis chips. IIRC, xgifb was just a fork of sisfb with
the strings changed. XGI was a combination of the old trident and sis
graphics teams. Most of the xgi cards were just rebadged sis cards
with the exception of the xp10 which was a trident variant and could
probably be merged with the tridentfb driver if there is one.
