The reason is the info->ChipFamily which I need for determining if 
tiling should be disabled is initialized in RADEONPreInitConfig as far 
as I can tell.
It should make no problems, the patch may look like that but I actually 
didn't move this around, but only moved the color tiling stuff to just 
below that.
