thanks for the explanation. My original problem "report" (on
freebsd-mobile) was that I'm getting about half the uptime on battery
under freebsd that I am on linux or winxp. I suppose my questions now
become:
- is this expected
- if it is, is there any way to tweak or otherwise "fix" it?

I understand that this non-optimal way of doing it is better for
non-interactive (I suppose server?) machines, but I am trying to
optimise for my laptop, which is only used by me.

any pointers would be appreciated.
thanks
