	Hello,

  Thanks for the tip, you're all right, it should be someone like hal
or dbus whick transmit it to applications like gnome-power-manager.

  In fact, trying some changes in /etc/acpi/*.sh scripts, I've found
that :
- the acpi scripts are well called when corresponding suspend buttons
are pressed (sleepbtn.sh for Fn-F4, hibernatebtn.sh for Fn-F12)
- these 2 scripts sleepbtn.sh and hibernatebtn.sh send a key to input
via acpi_fakekey, either $KEY_SLEEP or $KEY_SUSPEND
- only the $KEY_SLEEP is received by hal/dbus/gnome-power-manager, but
don't figure out why (and hal/dbus isn't well documented...).

I've found similar reports on the web :

but without solution yet...

I've tried on a Lenny system, but with same behaviour.
