I'm not sure if it's normal, a driver bug or simply
misconfiguration. Some website say that there should be power_level
file for the device in /sys, but it's not present on my system. Maybe
you can help me or just point to the correct mailing list for this.

Looks mostly reasonable to me. Did you try 'iwconfig wlan0 power on'?
If you're feeling adventurous, try iwlcore.no_sleep_autoadjust=0 and
'iwconfig wlan0 power on'. The combination works for me and decreases
power consumption a lot at the cost of a little bit of latency.

Yes, it didn't make an improvement.

It worked for me too, even if it just saved about 6 wake-ups per
second.
But I still wonder where the other parameters most users report about
have gone.

Look at power, not wakeups, for wireless stuff -- powering up the
receiver isn't cheap.

Look in debugfs. They've been renamed or removed in recent kernels.
