Unfortunately, I didn't notice I compiled compat-wireless (2010-05-21)
on user request against linux-image-2.6.32-5-686 and was using it
since then.
AFAICS Debian Bug #582906 can be closed.

$ dpkg -l | grep linux-image
ii  linux-image-2.6.32-5-686
    2.6.32-13                             Linux 2.6.32 for modern PCs

$ sudo lsmod | grep iwl | sort
cfg80211              100582  3 iwl3945,iwlcore,mac80211
compat_firmware_class     4683  1 iwl3945
iwl3945                45461  0
iwlcore                58688  1 iwl3945
mac80211              140617  2 iwl3945,iwlcore

On first sight it seems both patches fixed the issue here:

sd@seduxbox:~/src/compat-wireless/compat-wireless-2010-05-21$ cat
.pc/applied-patches
iwlwifi-fix-internal-scan-race.patch
temp.patch

By the way, iwlwifi-fix-internal-scan-race.patch alone did it not.

Any ideas for a testcase to be sure the problem is really fixed, now?
