Hi,
Yes, LINUX can indeed be installed onto a Palm handheld. Believe
it or not, you use your desktop machine as a dumb terminal over
the serial line, as the console!
I checked it out about a year ago, and at that time it was very
immature, and did not have a screen driver yet.
Check out
http://palm-linux.sourceforge.net/ I see there has
been some activity, somewhat recently...
