Is there any chance you could try bisecting the problem? Either just binary-searching the patches or by using the git bisect helper scripts?
Obviously the git approach needs a "good" kernel in git, but if 2.6.13-rc4-mm1 is ok, then I assume that 2.6.13-rc4 is ok too? That's a fair number of changes:
git-rev-list v2.6.13-rc4..v2.6.13-rc6 | wc 340 340 13940
but if you can tighten it up a bit (you already had trouble at rc5, I think), it shouldn't require testing more than a few kernels.
Git has had bisection support for a while, but the helper scripts to use it sanely are fairly new, so I think you'd need the git-0.99.4 release for those. But then you'd just do
git bisect start git bisect bad v2.6.13-rc5 git bisect good v2.6.13-rc4
and start bisecting (that will check out a mid-way point automatically, you build it, and then do "git bisect bad" or "git bisect good" depending on whether the result is bad or good - it will continue to try to find half-way points until it has found the point that turns from good to bad..)
