- Fix various bugs in the DRI support for the i830 and i845G (Keith

    Whitwell).
- Major rework of the 2D i830/i845G support, including:
- Improve VESA mode selection, and fix refresh rate selection.
- Don't duplicate functions provided in the vbe modules.
- Don't duplicate functions provided in the vgahw module.
- Rewrite memory allocation.
- Rewrite initialisation and save/restore state handling.
- Decouple the i810 support from i830 and later.
- Remove various unnecessary hacks and workarounds.
- Fix an 845G problem with the ring buffer not in pre-allocated memory.
- Fix screen blanking.
- Fix some HW cursor glitches, and turn HW cursor off at VT switch and
    exit.
- Don't attempt to use the i830's function 1 entity.
- Fix problems with option handling. (David Dawes).
- Add mode VBE-aware mode handling functions to the vbe module (David
    Dawes).
