That sounds like a sensible thing to port -- is there then a driver for
LCDproc for the lcd devices, or would that also need support? I'm
interested in getting LCDproc because it supplies a useful set of other
features too (menus etc) and I'm using my ARM machine as an MP3 player,
for which there already some LCDproc clients (including the infra-red
stuff I'll need).

Either way, if it's easy to get working - and really it should be - I'll
certainly consider porting LCD-Linux too anyway!

Cheers for the pointer on this one,
