I got mine working (THANK YOU SO MUTCH!) with the drivers from the CD (at
this point still the most recent drivers). I am talking about the Linksys WMP54G. The chipset is: Broadcom 4320 -- 0000:00:0a.0 Class 0280: 14e4:4320 (rev 03).
Since it is not listed on your site I thought that I could mention it to you that it works with ndiswrapper 0.6.
Keep up the good work!
