There are some build errors right now under certain configurations with apple-gmux. That's a bug, and the patch I sent fixes it. I'll test the patches that add switcheroo support for build failures under relevant configurations, but I'm not expecting any new problems since vga_switcheroo provides stubs when it's disabled.
