I've put together a new patch, all calls to err/errx has been changed to 
warn/warnx and put behind the verbose flag.
I also polished the devd code and made it work properly if the pipe to devd dies.

The patch is at http://shapeshifter.se/~fli/freebsd/powerd.patch
It includes all devd code so the previous patch is not needed.
