Forgot to add that I double checked, and cpufreq was enabled in the GENERIC kernel:

$ uname -a 
FreeBSD titan 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r298678: Tue Apr 26 17:29:01 PDT 2016 sd at titan:/usr/home/sd/obj/usr/home/sd/src/sys/GENERIC  amd64
$ cat sys/amd64/conf/GENERIC | grep cpufreq
device		cpufreq
