As noted in the launchpad bug, and in the associated ipw3945 patch:
The driver was not reporting the association.

I agree. Though, on that note, the wext is used with ndiswrapper now, so
oddities like this still occur.

Because wpa_supplicant_disassociate ignores the request if the BSSID

I agree. Fortunately, it seems the patch to ipw3945 mentioned earlier
nullifies this patch.
