I'm guessing that you've already tried this, but it never hurts to be
sure: does this machine pass memtest? :)

Unless someone recognizes special magic values from the register dumps
to point at any particular part of the kernel, the corruption could be
coming from almost anywhere. If noone has any better guesses, then
narrowing down the problem might be worthwhile: grab a vanilla
non-distro 2.6.18-1 kernel (from kernel.org) and see if you can
reproduce the problem with that, and then try to find the previous
release where the problem disappears. Or use git instead, which folks
say can do this bisection process rather well. :)
