Latitude E5400, WLAN 1397, Linux Drivers

Hello all,

Just got a a new Latitude E5400 that I loaded up with Ubuntu 8.04. All the hardware was recognized and worked great with the exception of the wireless card. The machine has a WLAN 1397 Dell wireless card and I desperatly need drivers for it. Any help would be greatly appreciated. 

Thanks, 

** EDIT: 

A "magical" apt-get -u dist-upgrade is using the open source wl drive and working great!
