So I figured out my OpenGL issue, but now I have a new host of problems. I think it has a lot to do with Windows 7 and Microsoft's aversion to OpenGL (and who can blame them... they do own the competing rendering library) since I was able to install Dell's (outdated) Vista drivers (btw, I'm running a Dell E1705 with a Mobility Radeon X1400). It fixed all of my OpenGl issues, Aquaria ran at a good framerate (with stipulations, more on that), but Prey and Doom 3 both ran perfectly well earlier today for the first time since I've had Windows 7.
As for the driver version, I'm pretty sure that Dell was just installing a custom version of the ATI Catalyst 8.6 drivers, so for people that don't own Dell laptops I would try that.
Now the new issue is that the title screen is all black and I can't see the option to start a new game, but there are other forums topics for that issue, so that's the last I'll say about that.
