It's true that both PRs are still open, but:

1) kern/114722 should fix your problem (CPUFREQ_CMP takes care of almost
   identical frequencies). Have you already had a chance to verify that?

2) bin/117375 talks about exactly identical frequencies, which should be
   handled by acpi_perf.c (1.26, line 303-306). However, the reporter
   (Cc'ed) of that PR runs FreeBSD 6.2-p8 which already contains the
   removal of duplicate entries (MFC from acpi_perf.c 1.24).

   @Benjamin Lutz: Could you please check if the problem still exists, and
   if so, whether the patch from kern/114722 fixes it?
