A8 performance monitor registers don't work in OMAP3530 / on Beagleboard

Hello -

I have been playing with the beagleboard and noticed that the user
performance monitor registers appear not to work.

I wonder if someone could tell me if this is pilot error or if this is a
known
issue. If it is pilot error - I would be most grateful if someone could
point
me in the right direction.
