I moved this from bugs to feature requests......
You say you have no interest in enabling the Intel graphics, I guess you mean you don't want to enable it in OSX but you want to use it in another OS that you boot, is that correct?
I'm not sure if Chameleon can disable hardware or if that is a feature the devs think would be useful enough to spend the time coding. We'll have to wait for one of them do drop by and enlighten us both.
Sorry I can't help more.
