524fd30c0c ATI Mach8/32 fixes regarding 1992 ATI Ultra drivers for Windows 3.1x: 
1. For some reason, background colors were always black under those drivers in 8bpp mode, added a tweak to fix it (as well as Clock colors).
2. Likewise for the red scrolling in pbrush or write, added a tweak to its bitblt read mask.
3. Don't call svga_recalctimings in the hdisp/vdisp ports directly, fixes screen size on said drivers without affecting other stuff.

1e71efc5bb More MGA fixes. 
Re-introduced the mystique read/write linear functions but with a check (!svga->fast) in the byte ones to make sure the generic svga linear functions are enabled when needed, this should keep compatibility stable while also fixing the amount of memory of NT 4.0's MGA Millennium drivers.
