About rebooting. I didn't have any, but I didn't play games. If you have swap partition on microSD, try to enable it in default.prop. Mount NITdroid partition in Maemo and go in /and where open default.prop with leafpad (or nano, or...). Then change value for persist.swap.swappiness= from 0 to 1. Also check if you have written right swap partition under persist.swap.dev=.

I have a question for one with more knowledge. Can I change persist.swap.dev=mmcblk1p3 value in persist.swap.dev=mmcblk0p3 to use swap on eMMC (which uses Maemo)? If I can, would be system any faster, cause I already have NITdroid on eMMC?
