Naw, don't bother with the peripheral callback unless the machine really needs it (if it moves around the chip select area, the leland arcade machines need it only because different games mapped the same hardware in different locations), the vast majority don't. The ip132 thing would probably look for 8250 serial ports so I don't know what it would think if it finds an 2661.

Edit: Definitely looks like there's a 2661 at 0xf9d0 so the others being at 0xc0 and 0xe0 seems quite possible.
