Do you see any frames from your specific client?

Yes. I can see this:
# tcpdump -i mon0 "ether host 00:1F:3B:79:41:6F"
[...]
10:10:03.013402 5.5 Mb/s 2462 MHz 11b -76dB signal antenna 1 [bit 14] Data IV: 14 Pad 20 KeyID 0

However, on wlan0 I don't see anything beyond the EAPOL packets.
Temporarily turning off WPA encryption let me successfully connect to my AP.

Aha, could you please try if loading rt73usb with nohwcrypt=1 helps?

(argh, brown paper bag)

I went through the compiled kernels again, and I've screwed up at the last
commit while bisecting (Sorry, Helmut!). The first bad kernel is a commit
later:

# bad: [f1aa4c541e98afa8b770a75ccaa8504d0bff44a7] rt2x00: Write the BSSID to register when interface is added

On the good side, I tested 2.6.36 with nohwcrypt=1, and it works. Yay!

Hmm, the patch itself that seems to cause the badness doesn't look bad.
However, closer inspection shows that the intf->bssid field may be initialized incorrectly.

I may be a long shot, but can you check if the attached patch helps?

Gertjan.
I tried the patch. Old behaviour: nohwcrypt=0 doesn't work, nohwcrypt=1 does.
I'm compiling the kernel with the revert of 'bisect bad' right now.
