Recently I've noticed small discrepancy in dmesg:
$ { zcat messages.2.gz messages.1.gz; cat messages; } | egrep "(deauthen|Linux version)"
...

Here we see 'wlan0' -> 'wlan%d' switch. I presume those lines go from firmware
(and not from userspace).
The card is an iwl4965

this seems to be fixed by the following commit which was recently
merged in wireless-testing
commit 59e7e7078d6c2c6294caf454c6e3695f9d3e46a2
Author: Thadeu Lima de Souza Cascardo <[email protected]>
Date: Thu Jun 2 17:28:37 2011 -0300
mac80211: call dev_alloc_name before copying name to sdata
This partially reverts 1c5cae815d19ffe02bdfda1260949ef2b1806171, because
the netdev name is copied into sdata->name, which is used for debugging
messages, for example. Otherwise, we get messages like this:
wlan%d: authenticated

are we still getting it?

Yes, with me too:
before patch application (3.0-rc2):
[ 63.837522] wlan%d: authenticate with 00:18:f6:aa:6e:25 (try 1)
[ 63.843805] wlan%d: authenticated
[ 63.844282] wlan%d: associate with 00:18:f6:aa:6e:25 (try 1)
[ 63.846887] wlan%d: RX AssocResp from 00:18:f6:aa:6e:25
(capab=0x411 status=0 aid=2)
[ 63.846891] wlan%d: associated
after patch application:
[ 69.472955] wlan0: authenticate with 00:18:f6:aa:6e:25 (try 1)
[ 69.479356] wlan0: authenticated
[ 69.479863] wlan0: associate with 00:18:f6:aa:6e:25 (try 1)
[ 69.482425] wlan0: RX AssocResp from 00:18:f6:aa:6e:25 (capab=0x411
status=0 aid=2)
[ 69.482428] wlan0: associated
Thanks for the pointer, Shafi.

I never ran 'wireless-testing' before.
Applied this commit on top of 3.0-rc2 and wlan%d switched to wlan0 back.
Thanks!
