According to the Intel manual cpu_model 6 has the same
perf counters as the other models of the p4 family.
Thus, the patch seems the right fix, except
that it would be better to use (cpu_model > 6)
instead of (cpu_model > 7).
Keir is right, oprofile should have the same problem
in native Linux. I guess we could submit a similar
patch for oprofile to the linux kernel mailing list.

That's where this fix belongs, then we'll pull it down into Xen.
