This issue seems to be solved in 12.10 Quantal beta 1.
I ran it with a live USB : wifi on channel 13 is detected and ubuntu connects successfully to it.
iw reg get => 00
iwlist wlan0 channel => all 13 channels
It's using the same brcmsmac driver as in 12.04.1, so I suppose it might come from an update in this driver?
In any case, jt's solved in 12.10. That's good news!
I'd like to help investigate if there is a way to backport this fix in 12.04, because it's a LTS.

I suppose I could test with an upstream or backported kernel. Which version should I test? https:/ /wiki.ubuntu. com/KernelMainl ineBuilds ? Another one?
