- * TODO:
- * - call STI in virtual mode rather than in real mode
- * - support for PCI-only STI ROMs (which don't have a traditional region
- * list)
- * - safe detection (i.e. verify there is a graphics device at a given
- * address first, not just read a random device's io space)
- * - support for multiple STI devices in one machine
- * - support for byte-mode STI ROMs
- * - support for just using STI to switch to a colour fb (stifb ?)
- * - try to make it work on m68k hp workstations ;)
