Thanks a lot.  I'm trying it out.  My apmd_flags were -A -Z 6.  It seems
adding -L didn't play well together, but, instead of figuring it out
what's exactly wrong, I just added -L alone to let obsdfreqd run in
peace.  

I'm using the battery right now.  It used to last an hour.  Let's see
how much it lasts now.  With the naked eye, it seems we got a slight
improvement, but it could be an illusion.

$ sysctl hw | grep perf
hw.setperf=0
hw.perfpolicy=manual

$ ps ax | egrep apmd'|'obsdfreqd
31819 ??  SU       0:00.00 /usr/sbin/apmd -L
60082 p2  R+/4     0:00.00 egrep apmd|obsdfreqd
68196 C0- S<U      0:00.12 /usr/local/sbin/obsdfreqd

Thanks!
