It is indeed there - but oprofile is still having issues.  It seems that 
the sample data that is being written out is invalid (files are filled with
only zeros, as far as  I can tell) , and opreport spits back errors, 
consistant with badly formed sample files.

We need some people who understand oprofile to take a look at whats happening
and diagnose it.
