I'm sorry, but I've made a typing mistake in my posting: I mean, that
there are two entries in '/proc/acpi/button'. Both are named 'power', so
it's impossible to get the listing of the second. The one, that can be
listed, has the entry 'PWRB'.
Cause both buttons, 'PWRF' and 'PWRB' are recognized at boot time, this=20
behaviour seems to be a result of a new directory structure.

Definitely not. I tested this a few times with the ACPI-patched kernel
and with a standard Kernel not patched and not with ACPI compiled in.

C2/C3 isn't supported with SMP-Systems?
