Well, it's all in the precise search string you try - and that is not 
one I tried.
But, that didn't do it, either.  I installed ALL the 218 or whatever 
updates, and tried the xaa option.  It turns out that XAA is enabled 
automatically, so that option wasn't accepted.  I tried the vesa driver, 
but it was seriously messed up, with a skewed video display.  I finally 
tried another option recommended in the Google search you recommended, 
and found that adding :
Option "NoAccel"  "On"
to the Device section of the xorg.conf file, made it work reliably, both 
for Axis and glxgears.  Killing the gears produces an error message, but 
EMC2/Axis seems to be reliable.

NoAccel seems to do it, and the performance is not bad enough in any way 
for EMC2 and general screen work.  (It is a 1.7 GHz Pentium, slower CPUs 
might not be so acceptable.)

Thanks,

Jon
