With 1.65 X crashed after short while so 450-112-1.5-1.8 is being used now. the only thing that seems to me is strange touch screen (non) responsiveness - although buttons seem to register the tap, several taps are required for buttons to in fact react. suspend/resume work, with quite often random wakeups. speed improvements - on startup i measured 3 seconds better time, in applications one has to see. seems quite interesting :), i will most likely want to try more MHz with tweaked kernel too.
