Use the proper driver.
Edit /etc/X11/XF86Config
Where you see the line
# Put clock lines here
Just above it insert the line
Options "noaccel"
That should work if you are using XFree86-3.3.6
If you are using XFree86-4.01 then look at the file
/etc/X11/XF86Config-4
and turning off acceleration is even simpler.
