Patch was added to CVS tree.
 
I would like to mention that you need to handle the possibility of some
of the PMC registers not being available. In dispatch_events() the
pfmlib_input_param_t structure carries a bitmask (r_unavail_pmcs), where
if a bit is set it means that the corresponding PMC is not available.
Take a look at pfmlib_i386_p6.c for an example.
