If I'm not mistaken, the wiki article on Hybrid graphics has ways to deal with the following scenarios:
- Intel + Nvidia
- Intel + ATI
But my laptop has ATI + ATI.
The solution in the wiki appears to work by blacklisting the Radeon driver, but if I did that wouldn't both of my cards stop working?

I was in the same situation as you earlier today and I'm using the open source drivers. I didn't think there would be a way to disable one of the two AMD cards but vgaswitcheroo turned out working just fine.
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
Running this command disabled the discrete ATI card but the other one continued to work fine.

Oh hey, it did work! Thanks, I just didn't really want to have things break if they didn't need to.
