did you try to count directly using the hardware timers 0,1,2, or 3?

Safraz, Thanks for pointing me to Avrora, it looks a very promising tool for my forthcoming research. With regards to the CPU cycle count problem of zero I was getting last week, I found the solution to the problem after much playing around. I thought it would be useful post the solution I found, as in the mailing list archive there is another messages relating to the same problem (with no reply). Basically, the file bb_cycle_map was not being populated. This file is one of the outputs of Power Tossim and contains the mapping from basic block identifier to number of CPU cycles in that basic block. I realised that this was due to the -g (debugging) option not being passed properly in the nesc app makefile. Note also, however, that Power Tossim does not seem to work with the latest version of CIL (1.3.6). I got it working with 1.3.4 though.
