I use C860 with Cacko1.22 and only apps from cacko feed. So my zaurus is pure Cacko.
I would like to add, that scummvm does not continue to run after a suspend. After pressing the power button to continue with scummvm, the display looks weird: even lines are from the game, odd lines are from QTopia and everything is 90 degree rotated.
Usually I pull out the SD-Card with the game data. this will make scummvm crash and Qtopia is shown again.
I don't know if this is a bug or just 'normal' behavior.

BTW: Cacko is realy a great ROM.
