Yes, it does. I did the followings:

- applied patch from comment #20 on a clean 2.6.27-rc4.
- enabled the DEBUG option in drivers/acpi/ec.c
- compiled the kernel
- booted into single user mode with parameters "acpi.debug_layer=0x00090004
acpi.debug_level=0x01f" (acpid is not running)
- pressed the POWER button two times: event reported through /proc/acpi/event
- pressed the LID switch two times: event reported through /proc/acpi/event
- unplugged and plugged the AC two times: event reported through
/proc/acpi/event

The other thing I recognised is that I get the same problem what I had before
in bug #8459, namely I can get the current temperature value very slowly,
usually between 1.5sec and 5.0sec.

$ time cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             47 C

real    0m4.749s
user    0m0.001s
sys     0m0.003s

I repeated the test when I boot to normal mode: the POWER and LID switch events
are reported. For the AC events to be reported correctly through
/proc/acpi/event I first need to stop the KLaptop applet.
