givemesugar, I haven't waded through all the info in detail but at first glance I'm wondering if you still have an old smelly drm for some reason, maybe new one built but didn't get installed properly ?

Your CPU shows clock of 800 MHz vs 2 GHz for countdown's, but IIRC the TK-57 runs at ~1.9 GHz when at full speed. Could be yours is just running slow all the time; might be interesting to pull clock info while glxgears is running.
