Fact is that with the 6600GT you won't be able to load any non-power of 2 square texture.
Either due to hardware or because the drivers enforce DX7 specifications.

I have that precise card and it loads all manner of non-square textures just fine and has done with every single driver version I've ever used. Since I used the card on a daily basis for 2.5 years, that's a lot of driver versions.
The 8xxx drivers, which emulate DX7 through shaders, just to mention that, do that as well.
If you play "cool kid" and use media not following DX7 specs, you can only lose, not win.

I have one of those too. I'll test to confirm or deny.
