No change here in HP Compaq land, except for the existence of this new
Quickstart Button1, no activity is reported via my HP WMI hotkeys or the
Quickstart Button, but rather through AT Translated Set 2 keyboard, as
usual - the same behaviour as not having hp-wmi or quickstart (eg. if I
unload the modules).

Maybe this HP documentation might help, there are ACPI tables and stuff
mentioned around page 8 ... http://dennisn.mooo.com/stuff/direct-launch.pdf
