LibSVGA support for newer ATI cards.

I have an ATI 3D Pro Turbo (4meg): Rage II+DVD acceleration: I have been looking into SVGA apps (Ie quake) and my card is not supported by the SVGAlib, so I have to use the default VGA (max res is 360x480) when my card can accually do up to 1800x1440.  When I do try the VGA max (360x480) my card almost slows down to a stop.  My guess is that it is using the main CPU, and not even bothering with trying to use the second CPU accelerator (which I believe does most of the 3D rendering).  The SVGAlib has not been updated for over a year now (I think), and the last release (1.2.11) doesn't support my card.  Does anyone know what I can do to get better perfomance from the card?  Does anyone have this card and have a hacked/working svgalib that performs very well? If not, where can I find information that will get this going?  I'd like to be able to take full advantage of the card.

Thanks for your guys/gals time.

At this time, there is no way to use the 3D Accelerator of
Rage chips in Linux, but this is not the reason for the slow
performance of Quake. Quake doesn't use any 3D capabilities of
your accelerator in DOS/W95 either.

There is preliminary support for Mach64 in SVGALIB (see mach64 help file that comes svgalib), but at this time it is also very slow.

You have two choices - play quake in lower resolution or use xquake (with some low resolution mode to get quake to work in full screen).
