Subject: - 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).
