Hi!
Uauh, It has been a while since Anyone posted here...and the bitcoin scene has changed so much. I think that actually anyone would care about this but I've started developing a gpu (well, qpu) miner for the raspberry pi. In theory (It is not finished yet) it should reach 1.5Mhash/second which is quite slow cause nowadays everyone talks about ghash/s. It is based on the excellent work made by Eric Lorimer (https://github.com/elorimer/rpi-playground). If anyone wants to take a look at the code or event write some of it, perfect!
Sergio.
