- 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).
