I can confirm that my MSI Wind U100 with the RT2860 card, running Ubuntu 9.04, cannot connect to my WPA/WPA2 network with driver version 1.8.0.0 or 2.1.2.0.
I got it working by deleting the existing driver, and installing version 1.7.1.1, which I got here: http://www.array.org/ubuntu/dists/intrepid/eeepc/binary-i386/rt2860-dkms_1.7.1.1_all.deb
