I'm trying to migrate from Linux to Openbsd on my laptop (thinkpad x201).
The first problem that i came across was that the Cpu fanspeed was
running constantly at 3500RPM.
After the acpithinkpad.c patch from jcs (and i modified to make it
work on the openbsd-current(link:
http://exclude.se/patch/jcs_mod_by_js.diff)
Another thing that i noticed is that the battery lifetime is really bad.
In Linux i get around ~5,5 hours.
In OpenBSD i get around 2 hours.
when i ran : sysctl hw.sensors | grep -i consumption.
the output of the cpu was 6W.
in Linux it's around 1,5W.
with: apmd -C and apmd -L it's the same.
dmesg: http://exclude.se/openbsd/dmesg.txt
Is there anyway to fix this?

Take a look at hw.setperf in sysctl. I think you are running at the
maximum cpu speed? On my 2.8GHz W500 I can run at 800, 1600,
2133 and 2801. 800MHz makes a huge difference. You have to
try different values for setperf to see what happens. sysctl will
also tell you the speed in hw.cpuspeed.
