Currently amd64 is broken with some/most drivers. Drivers appears to
use fpu registers.
I dunno how it ever worked, probably original developer(s) never
encountered drivers which use fpu registers.

I will probably fix amd64 support in this year.

Now when you mention this I may send patch for ndisgen(8) so it will
deny creating modules for 6.X API drivers.

NDISulator does not support 6.X NDIS API. You will need to find bcmwl5
driver. Note 5 vs 6 in driver name.
Editing inf files will give you nothing.
