The quick solution is to config -g your kernel, and extract statistics
via gdb

    gdb -x extract-reset-script -k -wcore unstripped-kernel /dev/mem

where extract-reset-script prints the current values, resets, and
then exits.

Otherwise, write a character device driver and matching user land 
facility to extract the information you want.
