I answer to my own post.
I have upgraded to ndiswrapper 1.0 today and now it works (at 54Mb/s,
with a D-Link DI-624+ wireless router).
The Netgear wg511 v2 works with ndiswrapper 1.0!
The proof: I send this e-mail wireless ;-)
I have also tried a D-Link DWL-G650+ and it works.
Thanks to ndiswrapper developpers,
