I tested Arjan's solution nevertheless and it seems to do the job. I can't find
the "TX Power requested" line anymore on dmesg output with that config option
enabled anymore and it connects without problems.
This is how it looks now:

I tested it quickly and not very thoroughly on the wpa-eap encrypted network at
university and it showed the same behaviour: no connection without
CONFIG_WIRELESS_OLD_REGULATORY and no problems with it enabled.

Thanks
