So, I've been playing with GPSman the last few days as found via this
page here, that has some interesting stuff on it:

gpsman is a tk/tcl app that lets you load a map image onto the background
of the mapping window, place 3 waypoints, and then track your position
against the map. I haven't got a lot of results to report but it 
sort of basically works with my novatel GPS receiver after some manual
munging of the receiver's output data.

Unfortunately, my Jornada doesn't have enough memory to adequately
load any decent sized maps and  swapping onto a CF card is probably
not a good idea.

Anyway, that's the summary.
