1. Convert the ramdac types into an enumerator. 2. Make sure the 8514/A compatible ramdacs are, if in VGA mode, using VGA compatible ports and/or, in 8514/A mode, the 8514/A ports when needed, fixes color issues in 1280x1024 resolutions on NT 3.1 and various stuff using the Mach32. 3. Add pitch initialization on reset, fixes 8514/A display drivers on various stuff on Mach8/Mach32 cards.
