XFree86 supports the following Western Digital SVGA chipsets: PVGA1,
WD90C00, WD90C10, WD90C11, WD90C24, WD90C30, WD90C31, WD90C33. Note that
the rest of the WD90C2x series of LCD-controller chipsets are still not
supported. The WD90C24 family is now supported including acceleration,
adjustable clocks and a full 1MB video ram even on dual scan systems (in
CRT mode). If you have trouble with the new WD90C24 support (not that we
expect you will), try specifying "wd90c30" or "wd90c31" on the `Chipset'
line in your XF86Config file. The WD90C24, WD90C31 and WD90C33
are supported as an accelerated chipset in the SVGA server; the
accelerated features are automatically activated when a WD90C24, WD90C31
or WD90C33 is detected, or specified in the XF86Config file.
