have I already answered?
I am not sure
well it seems, that 2.6.18 worked as expected but had other sufferings
with the latest git I see no difference
there is an new BUG warning in msi.c:680 - not the e1000 anymore, as far as
I can see it.

should I disable msi?
would this break something in an non obvious manner (because I already tried
a kernel without msi and it diden't seem to me that something broke.
on the other hand, it diden't give me the ACPI events back
and the echo reset > /proc/acpi/ibm/hotkey trick dosen't work either.
no idea what it did in the first place that made me think it was a good
idea... well, it did work once but I have no idea why. havent succeeded to
bring back the events a second time
should I try to unload / reload modules?
haven't done that yet
