I finally resorted to a "very dirty" installation method (mount iso, copy new img.boot, rename old, reboot, run installer and update over MOS3.1+Chrysalis 3.1, remove old img.boot, mount/install new Chrysalis, update via Grunch). So far seems everything works right (Ambeint loads faster, OWB brows faster, my net speed is around 200kb/s faster). Still, I haven't found the time to replace my old GFX with the newer Jim sent me. Gonna try it in the weekend and play some demanding games to test as benchmarks. Also, the cpu temperature module doesn't work (it's stuck at -0,3c). However, the biggest problem I have recently (it was present in 3.1 as well plus it was discussed here in moszone) is that MANY of YT videos have stopped working properly (I only hear the sound). YT downloader works. FYI, I have the most recent plug in enabled but no video :(
