Summary

  1. Simplified 4bpp rendering mode.
  2. Implement CRTC31 bit 0 functionality which enables/disables the vendor banks. Fixes Diamond Stealth 64 964 VRAM (VLB/PCI) detection on NT 3.1 (and possibly other cards) while keeping NT 3.1 347.1's full screen Command Prompt text normal without garbage using the 911/924 chips.
