Summary

  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.
