Hi,
the following commit breaks power button and lid button on my centrino notebook (MSI S260; branded as Medion SIM S2100).

With
git revert 53f11d4ff8797bcceaf014e62bd39f16ce84baec
on top of linus' tree I have no problems with power/lid buttons and my acpid configuration.
Suspend to disk/mem (at least for some seconds/minutes thereafter) with an unpatched kernel from linus' tree is another possibility to bring power/lid events back to life.
On my debian (etch) system I have following acpid(?) 1.0.4-3 configuration:
|gps@medusa$ cat /etc/acpi/events/my_lid |event=button[ /]lid |action=/etc/acpi/actions/my_lid.sh %e
|gps@medusa:~$ cat /etc/acpi/actions/my_lid.sh |#!/bin/sh |# lid button pressed/released event handler | |# echo "lid-event" | wall |echo platform > /sys/power/disk |echo disk > /sys/power/state
|gps@medusa:~$ cat /etc/acpi/events/powerbtn |event=button[ /]power |action=/etc/acpi/actions/my_powerbtn.sh
|gps@medusa:~$ cat /etc/acpi/actions/my_powerbtn.sh |#!/bin/sh |# suspend to disk (hybernation) when the power button has been pressed |# echo "power-button-event" | wall |echo mem > /sys/power/state
