I happened to try this today, but it's not so easy.  it used to work
but not anymore.

0. first of all you have to enable oprofile in kernel config and
install your own build

1. oprofile 0.9.3 does not work, so i need to put 0.9.4 in OE

2. log was filled with
   oprofiled: open of xxx failed: Invalid argument

   so now i'm trying to run gdbserver to figure what's wrong

anyway once it's up and running I will commit the necessary changes.
