privacy mismatch problems

Hi, so a while ago, I was getting lots of errors like this:
May 7 09:18:58 [kernel] ipw2200: U ipw_best_network Network 'faceplant
(00:15:e9:1c:16:60)' excluded because of privacy mismatch: off != on.
With these, I was unable to associate with my network. Occasionally, it
would somehow become happy (rmmod/modprobe sometimes worked). However at
some point, this became a total blocker and I was not able to get it
working again.
I don't really understand the problem, but after poking around in the
source a bit I found the code that's complaining in ipw_best_network:
5750 /* Verify privacy compatability */
5751 #if 0
5752 if (((priv->capability & CAP_PRIVACY_ON) ? 1 : 0) !=
5753 ((network->capability & WLAN_CAPABILITY_PRIVACY) ?
1 : 0)) {
5754 IPW_DEBUG_ASSOC("Network '%s (" MAC_FMT ")'
excluded "
5755 "because of privacy mismatch:
%s != %s.\n",
5756 escape_essid(network->ssid,
network->ssid_len),
5757 MAC_ARG(network->bssid),
5758 priv->capability &
CAP_PRIVACY_ON ? "on" :
5759 "off",
5760 network->capability &
5761 WLAN_CAPABILITY_PRIVACY ? "on"
: "off");
5762 return 0;
5763 }
5764 #endif
I added the #if/#endif and rebuilt (as a very simple and blunt test) and
things have been working quite fine since then. I've been running like
this for a month or more now.
So, my question is this: is there some better way to control the
"privacy" setting? I really don't expect that my "patch" is at all
sensible, but it works for me (TM).
This is all running on gentoo on a dell xps laptop with a 2915 card.
ipw2200-1.1.2
wpa_supplicant-0.4.8
ieee80211-1.1.13-r1
kernel-2.6.16-gentoo-r3
Thanks for any info.
Cheers,
Derek
