Perhaps the proper way to get the hal changes in is by submitting a patch to the hal and hal-info packages, or indeed upstream. The hal-info package is definitely where the /usr/share/hal/fdi/information/10freedesktop/10-sony-laptop-panel-mgmt-policy.fdi file lives, I'm not sure about the other ones in the package. I don't think a new separate package is the best answer.
