[jornada] Linux and GPS

All,

Lately I've been getting quite into the idea of bicycle touring. I
intend to take my Jornada with me for writing and getting on-line
at various locations while in town. After mentioning this to someone,
they suggested I ought to look into getting some kind of GPS working
with it.

I know that Windows CE has various tools for this, and I assume
hardware can be purchased that is compatible with the Jornada to do
so. However, are any of you familiar with hardware _and_ software that
can be used on the Jornada 720 with Linux? Particularly some kind of
mapping software.

Thanks,
