I have to admit I just looked at the issue again a few days ago.

I used a recent -current (maybe about a week old now) and I re-adapted
my config file from GENERIC. This added 

acpicpu*        at cpu?         # ACPI CPU (including frequency scaling)

and this silences the messages!

(If this is because everything works now, or the failing attempt is not
tried any more, I don't know yet).

However, twice now the kernel with this option has frozen completely on
me, within minutes after boot and login.

I also noticed that estd (for dynamic frequency scaling) didn't like to
work any more. It claimed not to recognize the cpu. I had to re-add

options         ENHANCED_SPEEDSTEP

even though there also is

est0            at cpu0         # Intel Enhanced SpeedStep (non-ACPI)

This is probably unrelated, though.
