present independently of is it loaded or not]
Problem Description:
After first suspend-to-ram (I use s2ram) and resuming system then, power button
stops working: acpid doesn't see it anymore. See logs attached for details.
Steps to reproduce:
1. Attach `/usr/sbin/s2ram -f -a 3` command to power button in acpid
configuration file.
2. `/usr/sbin/s2ram -f -a 3` -> system suspends
3. Press power button -> system wakes up, messages about disabling irq 9 are
written in kern.log
4. Press it again -> system should suspend again but it doesn't
5. Press it again and again -> still no reaction
