Jeff - can you test the kernels before-and-after this commit (with _no_ 
other changes) and descibe the differences?

Johannes - "not believable" is simply not an argument. If Jeff can show a 
difference, then your disbelief is totally irrelevant, and clearly shows 
that you are basing your beliefs on incorrect assumptions (like some 
specific version of firmware that isn't the whole story).
