- Disable acceleration with 24bpp due to apparent broken acceleration.
Accel at 24bpp was the cause of the crashes when people tried to use
any depth over 16. XFree86 doesn't support 24 either.
- Disable at < 8bpp, too.
- Add the other Rage 128 PCI IDs.
- Remove unnecessary setting of scissor registers (only default scissor
gets used).
help with ati, and future DRM drivers.
- Add new "ati" kdrive driver. It has ancestry in the r128 driver from
andersca, but took a detour through being the WIP SiS 300 driver on the
way. It supports Radeons (tested on QD VIVO and 7500) and Rage 128.
Current limitations include that it requires depth 16 and that the
other Rage 128 PCI IDs aren't included yet.
