Okay, although I have not had the chance to integrate it with top, it
would be exactly what you want.  The utility is under the directory of
src/test/pcpu/.  It's called cpustat.c.

Just type 'make' in the that directory, and it will produce the binary
for you.  When you run the utility, it will give you something like
the following, sampled on package building machine:

pkgbox:/home/hmp> ./cpustat
2 cpus
CPU-0 state: 0.00% user, 0.00% nice, 0.00% sys, 0.00% intr, 100.00% idle
CPU-1 state: 2.34% user, 0.00% nice, 3.13% sys, 3.91% intr, 90.62% idle
CPU-0 state: 0.00% user, 0.00% nice, 0.00% sys, 0.78% intr, 99.22% idle
CPU-1 state: 2.34% user, 0.00% nice, 3.13% sys, 3.13% intr, 91.41% idle
CPU-0 state: 1.56% user, 0.00% nice, 0.00% sys, 3.12% intr, 95.31% idle
CPU-1 state: 0.00% user, 0.00% nice, 0.00% sys, 0.00% intr, 100.00% idle
CPU-0 state: 1.55% user, 0.00% nice, 0.00% sys, 11.63% intr, 86.82% idle
CPU-1 state: 0.00% user, 0.00% nice, 0.00% sys, 0.78% intr, 99.22% idle

Hope that helps.  It would be nice if someone has time to integrate the
code into top(1), make things a whole lot easier; the framework for
retrieving the information is already there in cpustat.c, just a matter
of fitting it with top(1) specific parts.
