Kernel upgrade problem.
I have been looking high and low for this issue to have been resolved, but no one else seems to have it. I am using Slack 10 with the default kernel and am trying to upgrade to 2.6.7 but I keep running into a problem.
Every time a boot a kernel other than the default (this includes 2.4 kernels) the system is around 5 times slower! The bootup takes longer, my programs take many times longer to load, and my x server (x.org) is using 3 times the cpu than it should. De-optimizing from athlon to i386 with generic kernel optimizations helps a little.
This happened with Slack 9.1 with the xfree86 server as well.
Does anyone has any ideas on what could be causing this?

Any new kernel : 1.5 - 3.8 cpu

Any new kernel : 50 - 90 fps (no hardware acceleration or DRM on either)
