proc/acpi/wakeup

I was finally able to do some tests, here are my results.
- Samsung NP900X3C
- using linux-pm/linux-next with patches from Comment 219.

Upon boot, I get the following behavior:
- Power plug detection appears to be working no matter what.
- Lid switch is recognized (open/close states are reported correctly using acpi_listen), but suspend does NOT trigger.

However, after a while, (maybe after a few ACPI events?), the LID switch actually triggers suspend correctly; I'm not sure the issue is related.
It does not seem to revert to the broken behavior even after some time. It works both on battery and AC power.

Opening the LID does not trigger a resume, but tbh that was never the case on this machine.

Lv, if you have more tests in mind / need any logs just let me know.

Attaching my /proc/acpi/wakeup.

Thanks,
Andrea
