Some temporary video changes regarding the horizontal display.
...
S3 side:
Temporary changes to match the release (due to tomorrow) of 86box. Said changes are about the horizontal display of the tvp3026-based S3 chips.
IBM/ATI 8514-based:
Temporarily commented out the hblank side of it due to htotal bugs.
TVP3026 side:
When the upper clock selection bits are 0 and when extended VGA modes are set, double the hdisp.

MGA updates for the vram detection and stuff.
...
1. The Debian issue mystery lies around chain2_read/write being required when the LFB mapping is enabled too when MGA modes are set without blitting, however, when it is blitting, immediately tell chain2 to not interfere with the mapping. Fixes Debian once and for all as well as VRAM detection correctly while keeping existing compatibility fine.
2. Undev branch the G100 per above. (Revert if more bugs are revealed).
3. An AND with 0 is not tolerable as it nulls the LFB, fixes hang ups with Win2000 using the Millennium II and possibly the G100.
4. the Extended CRTCs now have a call for timing recalculation, fixes mode changes when blitting is going on.

Matrox MGA fixes:
...
1. When the 128K banking is activated, use a mask of 0xffff instead of 0x1ffff.
2. Debian uses standard VGA mapping when in chain4 mode and its lfb is adapted accordingly.
3. Fixed the decode VRAM mask on the Millennium II so that the vram is detected correctly and no more glitches.
4. Undev the Millennium II as well.
