- *  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 ;)
