012527fc4e MGA flicker fixes. 
It's time to end the flickers once and for all by making the start address correctly emulated in vblank_start when in power graphics mode.

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.

6eb05e14d5 ATI EGA Wonder 800+ and 18800 refactoring: 
1. Proper cleanup of the code.
2. Migrate the card in question to the VGA class list as it's actually a rebadged VGA Edge (thus 18800).
3. Some VGA only features are not supported on this card and are documented in the recalctimings.

f5642ab1c3 MGA fixes 2: 
1. Reverted the packed chain4 and fb_only sides to 1 when extended mode is set, but with the call to svga_recalctimings removed from port 0x3df due to mode issues, this should fix all the MGA mode issues I know.
2. Cleaned up the rendering order in svga_recalctimings, especially 4bpp and 8bpp.

c62182cd2e MGA Fixes: 
1. LFB access is now done properly through the right svga_read/write linear calls.
2. Lowres 8bpp mode and Packed/Extended 8bpp+ mode don't mix together, fixes Debian Woody matroxfb module when testing the modes while keeping other compatibility intact (basically enable packed stuff only when gdcreg5 bits 5-6 are 0 when extended mode is set).
3. Small cleanup in the line accel stuff.
