1.  Supported hardware

The s3virge driver in XFree86 4.3.99.903 supports the S3 ViRGE, ViRGE DX, GX,
GX2, MX, MX+, and VX chipsets.  It also supports Trio3D and Trio3D/2x chips.
A majority of testing is done on ViRGE DX chips, making them the most stable
to date.  This release has added support for doublescan modes on DX.

This driver is moderately stable, however please use caution with any new
install.  Please report any problems to <XFree86@XFree86.org> using the
appropriate bug report sheet.

   o Fully accelerated support for S3 ViRGE family video adapters

   o uses linear frame buffer

   o supports resolutions up to 2048x2048

   o supports color depths of 8, 15, 16 and 24

   o full use of video card memory for acceleration caching when visible
     framebuffer leaves extra memory

   o XVideo on DX, GX, GX2, MX, MX+ and Trio3D/2X at depth 16 and 24

   o Doublescan modes on DX, possibly others (untested)

3.  Configuration:

The driver auto-detects RAM size, RAMDAC and ClockChip. Do not bother putting
these in your "Device" section.
