Hi Brand and Finn,
I just want to let you guys know that I was able to get the serial port stuff setup and was able to capture the last kernel message before the Powerbook would shutdown on start up (thanks again Finn for the serial cable tip!) Here it is:

We currently don't have a driver for any m68k
mac floppy drive in the

point, someone posted a
proposed driver that worked in at least some
systems, but I don't think
it ever got finished or included.
Laurent Vivier wrote swim_driver and committed it to
the 2.2 branch on
sourceforge 3 years ago. I believe it supports all
m68k macs, other than
those models covered by the swim_iop driver.
It also does not support the AV macs, which do not use a
SWIM chip. In
theory, it could support the models that would normally use
swim_iop
by bypassing the IOP chip, but that means disabling ADB. We
used the
bypass feature to get the serial ports working with the
normal driver
on those systems, but the only drawback there is the extra
CPU time.
