[Soekris] Extra LED (Design/Circuit/Software suggestions)

Hi,
We are in need of an extra software controlled LED on 4826.
The red error led is already in use.
What would be the easiest way to achieve this?

I guess the GPIO pins on JP3 probably is the way to go.
Can they power a LED without a power circuit?

Iregardless on how this is solved I am currently also having problems with
the GPIO driver by Martin Hejl.
Upon insmod it gives me:
4801gpio: Version 1.2.0+daj0.1 (C) 2003 Martin Hejl & Dave Johnson
4801gpio: Geode GPIO base 0x6100
4801gpio: PC87336 not detected

If I insert the scx200.o module before (Why SCx200 on a SCx100 chipset?!)
I instead get:
scx200: NatSemi SCx200 Driver
scx200: GPIO base 0x6100

Followed by a:
4801gpio: Version 1.2.0+daj0.1 (C) 2003 Martin Hejl & Dave Johnson
4801gpio: Geode GPIO base 0x6100
4801gpio: can't allocate I/O for Geode GPIOs

Thanks in advance!
