Oh. Boy.

I'm on a desktop using a desktop chip,using a Radeon 9100, lspci says:

0000:01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R200 QM 
[Radeon 9100]

So wtf is going on? I've done the test several times, with it on, ~2100, with 
it off, ~2000. (Not that I'm actually complaining, its just that if it gives 
more people speed boosts, its worth looking at why)
