As someone who has done some of this sort of work, I'm sorry to say that 
most mac68k device drivers aren't going to be able to be shared.  The 
hardware interface is, um, "different," and you have to change some of 
your assumptions at a very fundamental level.

The `sbc' driver in the mac68k port uses the MI 5380 code in /sys/dev/ic, 
but as it currently doesn't support as many devices as currently work 
with the `ncrscsi' driver and it's slower, it is not a reasonable choice 
for the GENERIC kernels.  In fact, I'm strongly encouraging that people 
use it only for experimental purposes. :-)

Other than the SCSI driver, though, I'm having a hard time thinking of 
what common driver code the mac68k port might be sharing with the
