686 kernel wastes CPU power

[Matt Patterson]

I have tried rebooting, I have also tried disabling all acceleration
features in xorg.conf. Neither caused any change. The only thing that
changes performance is to boot into a 386 kernel. Even if I am sitting at a
console, if xorg is running on a different console then there is wasted cpu
power.

I guess I could recompile a kernel, but that is a bit annoying at the
moment. The machine is more than fast enough on the 386 kernel, and I use
nothing that would care which kernel I run, so I will just stick with what I
have. I just figured other people would want to know. I have seen MANY
people complain about the high xorg utilization problem.
