Perhaps you could add a .desktop file in the gnome-extra/hal-device-manager ebuilds so that it's accessible from the Applications menu? All that's necessary is to 'inherit eutils' and add this to src_install: make_desktop_entry hal-device-manager "Device Manager" "/usr/share/hal/device-manager/fdo-logo.png" "System" fdo-logo.png is used by the program itself, although hal-computer.png might also be appropriate. Thanks for your work!!
I have added hal-device-manager-0.4.5 to cvs with this addition.
