measuring time spent in kernel

"top" and similar tools don't seem to capture the time spent in kernel
which isn't on behalf of a user process.

I vaguely remember mention on this list of a tool that soaks up as many
cycles as it can get to obtain an accurate measurement of the true
system time.

Can some one give me a pointer? I've had no luck with Google...

thanks,
