We definitely can. I'm not against it, I just think it's a pretty heavy 
hammer for the problem. But as long as it provides reasonable data I 
don't care.

The thing I care about is providing reasonable data so that the AMD 
Bulldozer CPU can be detected in either way depending on the choice of 
the management app.
