Seems to be channel 1. I realized that I have actually 3 AP:s at my
disposal right now and powered them on. The scan at boot still says it
scans only 2 channels, but the output actually shows all three of them
plus the one next door (the channels for the APs are 1, 6, 11, 13 so
that's not a problem either).

The result looks like this:

wlan0     Scan completed :
          Cell 01 - Address: 00:00:00:00:00:00
                    ESSID:""
                    Encryption key:off
                    Channel:0
                    Quality:95  Signal level:0  Noise level:161

This is in the same environment as above, so I'd expect to see four
APs instead of this one obviously broken.

Good to know :)

Ah, I didn't spot that when I downloaded the sources. Building from
that tarball gave me a functional driver (well, apart from the
scanning thing).

Thanks again! :)
