Hmmm.  I'm not sure if the Powerbooks even use the same chipset (ZS8350)
as the other Macs.  I _think_ that our serial driver is pretty specific
about supporting that chipset only.  If the PBs use a different chip, then
I'd be willing to wager that you're probably out of luck WRT the serial
ports.

Maybe Bill Studenmund can clarify this for us?
