Thanks François. I installed 3.3-4mdk per your advice and I'm encouraged
by the results. But... Is there a reason for why I only get pseudo-dma,
even though I have agpgart installed? I attach a few config files FYI...
gears gives me ~200 FPS but q3demo is really unplayable - too jerky and
garbled sound and bzflag just gives:
Loading required GL library /usr/X11R6/lib/libGL.so.1.0
@@Created GLX Context..
and nothing more.
Any help appreciated.

#
# Do not ever fall back to software rendering. Use with care, almost
# guaranteed to cause improper rendering.
# mach64_skipdma = 0
#
# If set the driver will fill the command buffers with rendering commands
# but the buffers will not be sent to the card. Used for performance testing
# and debugging.
# mach64_drawtest = 0
#
# If set the driver will do some initial rendering tests upon startup.
# Useful to see if the driver is being loaded correctly.
# Intel i810 specific variables:
# i810_dma and i810_dmasize are the most important variables in the
# Intel i810 section.
# i810_dma = 3
#
# Valid values: 2 - 3
# 3 (default): the driver will default to using 2 large dma buffers
# to transfer commands asynchronously to the card. This is the optimal
# setting and has been stable on all tested systems.
#
# 2: Physical buffer is used for commands. Synchronous DMA is used to transfer
# commands to the card. This is a reduced performance mode for testing.
#
# 1 and 0: not implemented.
# i810_agpsize = 8
#
# This is the size (in MB) of the agp buffer allocated to hold
# textures, backbuffer and depthbuffer. On i810e and i810-dc100, the
# four megabyte video cache is used to hold the depth buffer instead.
# S3 ViRGE specific variables
# The lightmap hack is described in the readme. Won't work with DMA
# yet.
# s3virge_lightmap_hack = 1
#
# Dma...
# 0 - no DMA is used.
# 1 - a 4k command DMA buffer is used
# 2 - s3virge_dmaadr must be set and a mem= line in lilo.conf
# must be used. Set your system memory to something shorter
# than your actual memory (eg if you have 128M of ram, put
# mem=124M in your bios, and set s3virge_dmaadr to 124, and
# s3virge_dmasize to 4)
# This is synchronous DMA. a 64k command buffer is used.
# 3 - Same as 2, but asynchronous DMA
# s3virge_dma = 3
# s3virge_dmaadr = 124
# s3virge_dmasize = 4
