In Lucid BCM4322 wireless adapter will not connect to WPA encrypted networks using any driver option available

[LSL]

I can connect to unsecured wireless networks with this card, but anything with WPA encryption will never connect

I can confirm this problem as well, with Lucid (beta 2), on a MBP (5,4), with the following from lspci:

Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

Temporary workaround (tested, verified):

1.) Run: modprobe -r wl
2.) Remove: bcmwl-kernel-source 5.60.48.36+bdcom-0ubuntu2
3.) Install: bcmwl-kernel-source_5.10.91.9+bdcom-0ubuntu4
4.) Run: modprobe wl
5.) (Optional) Stop dpkg from updating, run: echo "bcmwl-kernel-source hold" | dpkg --set-selections

The previous version of the kernel source driver is able to find hidden access points and complete handshakes without error.

Syslog results (5.60.48.36):
==

The above messages repeat several times, until ultimately rolling back to the previous kernel source rpm version.

Any computer I own with a broadcom chip in it has this same problem still, and the b43-fwcutter only works on one of our machines
