The issue is partly fixed.  I now see the following frequency levels if,=20
and only if, I booted the laptop on battery power:

# sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 1200/0 1050/0 900/0 787/0 750/0 656/0 600/0 562/0=20
525/0 450/0 393/0 337/0 300/0 262/0 225/0 187/0 150/0 112/0 75/0 37/0

Note that the native processor speed (1700 MHz) is not listed, and setting=
=20
the speed below 150 hard-hangs/freezes the laptop.

When booting with AC-power the laptop does not report any freq{,_levels}. =
=20
It does not matter if I remove the AC-power once the computer is up and=20
running, I always get this:

# sysctl dev.cpu.0.freq
dev.cpu.0.freq: -1


=2D-=20
