Some hardware initialization that was previously mixed with it is moved to viafb_setmode. As are the calls to the newly created function. This is yet another little step towards controlling each IGA on its own. As this patch really aims too mimic the old behaviour no regressions are expected. However I noticed that 8bpp (or 6bpp?) seems actually a bit broken before and after the patch.
