I'd just compare a recent kernel with something older, pre Fri Oct 19

Then download ctxbench, run one instance on each core, bound with taskset.
http://www.tmr.com/%7Epublic/source/
(I don't juse ctxbench myself, if it doesn't work then I could post my 
own app. It would be i386 only with RDTSCs inside)

I'll try to run it on my PentiumIII/850, right now I'm still setting 
everything up.
