I've compiled kbd-1.15.3 from here on Scratchbox, taking out everything within share/ to save space (there didn't seem to be anything useful anyway, just a bunch of locales, fonts etc). Both loadkeys and dumpkeys work on my N900; I haven't tried any of the others as of yet, but can't see a reason why they shouldn't either.

Someone could package it up nicely, if they so wished

EDIT: Heh, I hadn't even looked at pali's posts from last night - seems like he was one step ahead of me, as usual :P
