Warns about using an unexpected kernel on boot, then sleeps for a minute, boots fine after that though.
System information still reports being 3.5.2 (I'm fairly sure it flashed the image correctly though, since it has the 3.5.3 feed setup by default as well as the 3.5.3PreRelease kernel).
I managed to break the opie configuration by going in to the timezone setting dialog then pressing back (just shows the background and the next and back buttons, disabled).
Package manager's confirm package list changes dialog is too small, only the tops of the okay/cancel buttons are visible.
But, and for this I will profess my love to you lot, it now wakes up for alarms again, which is something I was greatly missing in 3.5.2.
That's all I've checked so far, will continue playing, seems nice overall though.
