Patch has been committed, along with an addition to use a taskq to clean
up the extra devices. You should find that all this works fine and
/dev/apm is cleaned up.
To upgrade, you should install the /etc/ scripts, acpiconf, and the acpi
kernel module. Installworld/mergemaster take care of this. Old
binaries of acpiconf will continue to work fine with just a message
printed once on console that the old API is deprecated.
