The ISA IO space uses fe000000-fe0200000. OpenBios uses 0xfff00000-0xffffffff. This leaves very few possibilities. Alternatively we can map the whole MacIO device at a fixed location which also makes the location of the serial ports fixed. The G3 beige uses f3000000-f307ffff for the MacIO device. -- .''`.
