Westmere I still hold off because the oprofile user land doesn't have the correct event list yet.
BTW I was thinking in this case to only add the model numbers to the user code and just let it handle arch_perfmon from the kernel.
This should work currently fine and avoid the problem that you need to update user land and kernel in parallel for a new cpu type.

Yes would make sense. I'll ask around if there is a consolidated list somewhere that could be used as a base.
