I've tried it, and it doesn't solve my problem. With the patch 
applied, "opcontrol --list-events" seems correct, but I still get no data 
from OProfile, neither from the CYCLES nor the INSTRUCTIONS_GRADUATED 
event. /var/lib/oprofile/oprofiled.log just repeats:

   Nr. samples lost cpu buffer overflow: 0
   Nr. samples received: 0
   Nr. backtrace aborted: 0

I tried both on the full machine and on only the R12000 rack with identical 
results. The R12000 rack alone also has the original problem with large 
system overhead.
