  I'm sorry, do you have some test results of performance or some data
about microarchitecture difference ?

It's not too obviously how to prepare chip w/decreased MP performance,
but working correctly in SMP environment. For example, I should
suppress something like split transactions handling etc. It looks too
expensive to prepare special chip with a bit different microarchitecture.
