Yup, I meant that we need to signal acpid. For Debian the postinst 
script should call the init file for acpid to do it (that's the clean 
way, I guess), but for other distros (install.sh) it should probably be 
a killall -HUP acpid or something like that, because invoking init 
scripts in a distro independent way is close to impossible in my 
experience. :-/
