This problem is only is -mm (still in rc5-mm1),
not in any -rc (especially not -rc5).

I didn't get any response about this report. But, looking at
the code, I finally thought that's a feature, not a bug.
The entire code for this /proc/acpi/buttons disappeared
from drivers/acpi/buttons.c
So I guess ACPI guys wanted to drop it ?

Button events are still reported well in /proc/acpi/events.
I don't need anything more.

Thanks,
Brice
