I think so, yes.

The ia64 perfmon has some features perfctr doesn't have,
but my perfctr API changes will allow perfctr to grow its
feature list and adapt to HW changes without breaking the API.
Its unlikely that perfctr will ever implement everything
perfmon does, but multiplexing and overflow sample buffering
are two features that should be added at some point.
