I was unable to reproduce the problem with the following configuration:

   FW: the latest released version (
http://www.laptop.org/teamwiki/index.php/Tech:Wireless )
   driver: our branch of the driver (
http://git.infradead.org/?p=libertas-2.6.git;a=log;h=cozybit )
   Host: IBM ThinkCenter + 8388 dongle
   AP: Linksys WRT54G

Details follow...
