OK, my suspicion is confirmed. With the ac adaptor plugged cpuspeed will no run and the system will not leave 600MHz. With it unplugged and running on batteries cpuspeed works fine. running glxgears it jumps to 1500MHz as it should. I now wonder if this has been the problem all along, and it just came and went causing the intermitten lack of cpuspeed... I would if its the ac adaptor that is faulty or (worse) my system... Hmm.
