Hal was removed from the startup process in Lucid:
https://wiki.ubuntu.com/LucidLynx/TechnicalOverview
but is still used for other applications. I can't recall the command to
check for existing applications that depend on hal, but I'd recommend
you keep it.
https://launchpad.net/ubuntu/+source/hal
http://projects.gnome.org/gnome-power-manager/hal.html

What you see are 'Warnings' from gnome-power-manager:
https://launchpad.net/ubuntu/+source/gnome-power-manager
https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager

I've yet to figure out the source/meanings of the warnings (I get them
as well on all of my machines) & have even purged and reinstalled
gnome-power-manager in attempt to resolve the problem. However, they are
'Warnings', so ignore (or attempt to debug) them.
