yeah, i find it useful too. The main reason is that most of the systems 
out there have like 2 freely defined events. Only Nehalem and i think 
Power7 has more.

OTOH ... maybe we should just do it, as most measurement and tuning is 
done on modern hardware. I'll try your patch in the perf tree - if too 
many people complain we will undo it.
