The chkconfig command was very ingenious, I had not thought of that
myself. And you completely nailed it by spotting the Xautocconfig
problem, I had forgotten about that one. You can also disable it by
going into /etc/rc.d/ and from there into the directory for each
runlevel. Each has a symlink pointing to the Xautoconfig script located
at /etc/rc.d/andcan'trememberthrest (sorry, I'm at Mac OS X now!). After
you erase the symlinks reboot and pass the kernel arguments, specifying
the "aty" driver, which is the one the Mach64 card uses. That should
give you accelerated video.
Enjoy your learning, I do that everyday. Yours,...
Juan.
