I can provide accounts on the MIPS box in question if it would help.

Complicating things is that on my machine it has a 64-bit kernel but a 
32-bit userspace.

The errors are below.

I can patch around the first and replace pfmon_detect_unavail_pmcs() with 
pfmon_detect_unavail_regs().  But if I comment out the offending 
breakpoint lines and try to use the resulting pfmon it just gives 0 values 
for all measured counters (though that could be a problem with the kernel 
too I suppose).
