Does Beta TC 8 help this any?  There were some Mac related fixes in the kernel that went into that.
Comment 2 William Brown 2012-11-13 23:19:10 UTC 
TC8 provides support to getting the radeon card to work at boot, but the i915 still changes the display to black when attempting to switch to it. See https://bugzilla.redhat.com/show_bug.cgi?id=765954
Comment 3 Josh Boyer 2012-11-14 13:19:31 UTC 
OK, we'll close this one out and track the intel issue in the other bug.
