So, has anyone tried BIOS 3305 under OSX yet? I've got a nice little hackbook now that i've upgraded to a dell 1390, and I don't really want to be the first to try a new BIOS in case it causes issues. ~2:30 hrs battery life is good, but if 3305 does make a difference, i'd be excited to upgrade! (And there's always the chance it fixes sleep mode too!) Let me know what your experience has been!
