Eliminate bogus rate check in fbdevModeSupported. Hmm. Potentially bogus 

rate selection necessary for Mac fbdev
Don't know about fb changes to pixmaps, so can't track dirt.
Add Mac specific 1280x854 mode. Warn when requested mode isn't found.
Add ability to soft-boot video cards.
Add region expand request. FIXME: need test cases
