On Linux, a simpler way can be to look at /proc/interrupts - e.g.
(probably Linux-version- and possibly config-specific):
$ (cat /proc/interrupts; sleep 10; cat /proc/interrupts) | \
awk '/timer/{prev=now; now=$2} END{printf "%dHz\n", int((now-prev)/10)}'
Why there isn't a /proc entry or sysctl that gives the frequency
directly I don't know...
