Ima, thanks for your advice on the traces left by having the power kernel installed - I wasn't aware of this. Gonna have to chance this though. Knowing the margins on these products I think I'll be OK (i.e. they spend all of 20 seconds confirming it doesn't working, throwing it in a bin and then posting out a brand new one)... else, well if they do go to the trouble of looking in the logs and getting shirty about it - it's only a (now broken) phone.

Do you know a way to charge even when it doesn't seem to want to? I'd have thought charging was lower level than the kernel? I.e. handled by on board programming. Else I'll have to hook up with someone I know with an N900 and swap b8trez for an evening.
