Sorry if this is slightly off-topic. I just saw this at
<http://ryeham.ee.ryerson.ca/uClinux/>:

"The Linux/Microcontroller project is a port of the Linux 2.0 to systems
without a Memory Management Unit. At present, only Motorola MC68000
derivatives are supported. The first target system to sucessfully boot is
the 3Com PalmPilot with a TRG SuperPilot Board and a custom boot loader
they put together specifically for the Linux/PalmPilot port. Thanks guys! 

The port of Linux to systems without MMU was done during the last week of
January, 1998 by The Silver Hammer Group Ltd's programming team, Kenneth
Albanowski and D. Jeff Dionne. As with all ports of Linux, this is free
software under the GNU Public License."

Would be way kewl to run NetBSD on an old 68000 ;-)
