Can you give the version of NetworkManager you have installed?  I'm
assuming it's 0.6.4-6.

Just tested this on a RHEL5.1 box with kernel 2.6.18-53.1.4.el5 and
ipw3945 and wpa_supplicant, and it's a bit flaky even without
NetworkManager, but that can be either the kernel or the access point
itself (a WRT54GC).

Can you try to run wpa_supplicant like so:

/usr/sbin/wpa_supplicant -ddd -i eth1 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf

And grab the output?  That should help isolate whether it's something
NetworkManager or the driver or the AP or what.

How far away from the AP are you?
