I got hwpmc to compile (but only as module)
hwpmc: TSC/1/0x20<REA> P6/2/0x1ff<INT,USR,SYS,EDG,THR,REA,WRI,INV,QUA>
but when I try to use pmcstat I receive this error message:
pmcstat: ERROR: Initialization of the pmc(3) library failed: Device not 
configured

kldstat lists hwpmc.ko as loaded and I have options HWPMC_HOOKS in my 
kernel.

Any idea what's go wrong?
