The machine stops booting right when it attempts to switch modes during boot, to a higher mode than the default VGA one. Machine doesn't ping and is otherwise unresponsive so that a hard reset is the only thing that helps. Reverting that patch ontop of -rc7 fixes it and the machine boots just fine. Thx.
