e9f0af21a0 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.

* Fixes cursor disappearing completely in Matrox cards in some cases.

0240f11bbe 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.

7198b78069 Couple of changes in the video side.
1. Second attempt to fix the banking in the Cirrus (sigh, why doesn't banking get nulled automatically...)
2. Introduce a new timer to the 8514/A side so it won't slow the VGA clock down it was shared before.
