I don't think this is because of the restricted vs. open change in
ipw2100. NetworkManager already defaults to restricted. Do you have
your access point set to broadcast its SSID and use Shared Key
authentication? You might also try resetting NM's configuration:
$ gconftool-2 --dump /system/networking/wireless/networks > wlan.xml
$ gconftool-2 --recursive-unset /system/networking/wireless/networks
I'm also running the ipw2100/NM combo and while there does seem to be a
problem with AP scanning, I can usually make it work after a couple of
retries. I intend to spend more time with the issue but it seems that
the problem is in ipw2100's scanning. The output of "iwlist wlan0 scan"
is not very stable and that confuses NM. I've also seen cases where
NM's scans result in a firmware reset. What does your syslog say?

As I said, restricted is already forced.

It should actually be the other way around. NM currently doesn't work
with open system authentication, since there are problems with WEP key
failure detection. Dan posted an explanation on the fedora-test-list

Take a look at src/NetworkManagerDevice.c:826. But note that
auth_method is never set to NM_DEVICE_AUTH_METHOD_OPEN_SYSTEM.
