al least 99.9% of chipsets support remapping, since the system BIOS
lives in compressed form on the EPROM, the PCI VGA BIOS has
to adapt itself to the base IO port assigned by plug&play,
so it needs read+write access to the shadow RAM at init time.

The problem is to get good/useable/valid datasheets in most cases...
