Subject: How to use perf to log page faults

Hi,
 From the docs it seems that perf may be useful for logging page faults. 
I tried
perf record -g -d -f -e page-faults <mycommand>
but all I got were PERF_RECORD_MMAP events.

I'm using 2.6.32. Ideally I'd like to collect fault addresses and 
userspace stacks that caused them. Isn't this what the page-fault event 
is for?
