I decide to give my Gentoo box a try for the bcm43xx driver mentioned in the Ubuntu 6.06 LTS review. I just follow this HOWTO, and it works! The only drawback is that the 802.11g(54M) has to run in the 802.11b(11M) mode, and iwconfig eth1 essid anyseems not working, you need to specify the essid explicitly.
Still a great reverse engineering work! Please keep working on it, I would use this module and help on testing it.
