According to Eben the Nokia N900 display should work but I don't think there's any drivers as of yet.

It works fine on all USB sockets I have used. I suspect though that my monitor allows more than 500ma. I wonder whether it has the 'intelligence' to complain (8-)# My M/C helmet, BT keyboard charger and Apple chargers will also do. The GPIO header looks great. Other that power and ground it looks user-definable. I must see if I can get the QL I2C devices working. I presume drivers do not yet exist. Also an LCD monitor (via ribbon to the motherboard) would open the way for long lasting battery powered units. At present it is not possible to ssh in - 'connection refused' - and sshd is running. Where do I investigate I wonder?
