It's in fact possible to bisect qemu-kvm.git.  If you end up in 
qemu.git, do a 'git bisect skip'.  If you end up in a merge, call the 
merge point A, bisect A^1..A^2, each time merging A^1 before compiling 
(the merge is always trivial due to the way we do it).

Not fun, but it works.  When we complete merging kvm integration into 
qemu.git, this problem will disappear.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
