Hi,

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
