yes; but quite a long time ago; didn't make a difference

those boards go rather low in their minimal frequency (about
200-300Mhz if not even lower) and in at least 8 steps; acpi_ppc, which
works for me, seems to take into account only the four most powerfull
states (about 1Ghz being minimal then)

might be a "piste"

PS, while here, and totaly unrelated, rev 1.252.2.7 (MFC "un-neede
singl-threading code") of kern_fork.c to releng_6, seems to break
things for me in a 4-way SMP (twice dual-core) amd64_releng6 box when
forking procs in java. I'll triple-check before once again sending a
bogus problem email but I got plenty of strange things when upgrading
a production box to recent releng_6 (for sake of testing ata-promise
TX4 patch), which disappeared after reverting to 1.252.2.6. fyi
