(--) SVGA: s3_virge: Using hardware cursor
(--) SVGA: Using XAA (XFree86 Acceleration Architecture)
(--) SVGA: XAA: Solid filled rectangles
(--) SVGA: XAA: Screen-to-screen copy
(--) SVGA: XAA: 8x8 pattern fill
(--) SVGA: XAA: 8x8 color expand pattern fill
(--) SVGA: XAA: CPU to screen color expansion (bitmap, TE/NonTE
imagetext, TE/NonTE polytext)
(--) SVGA: XAA: Using 8 128x128 areas for pixmap caching
(--) SVGA: XAA: Caching tiles and non-transparent stipples
(--) SVGA: XAA: Horizontal and vertical lines and segments

I agree that XFree86 isn't very impressive on many accounts, I would
just notice that my S3 ViRGE is NOT ACCELERATED AT ALL with SVGALib and
that XFree86 XAA reports solid filled rectangles, screen-to-screen copy,
color expansion, pixmap caching and others...

That seems more than sufficient for me, when you take into account that
SVGALib has no acceleration whatsoever for my ViRGE.
