Indeed :)

I did notice that the card in question wasn't on that list. But my own 
experience with ndiswrapper and wifi cards were far less than 
satisfactory- the firmware always got in the road. But I may have just 
been too stupid at the time :)

No they are absolutely not of poor character, I agree. Some messages can 
be misconstrued, though, in that the replies can be terse and more 
logical than sympathetic. Sometimes it is easier to replace with a 
different card than flog a dead horse, although a user may take offense 
for emotional or financial reasons more than logical.

Mitigation is a difficult path as I have found personally, although NDIS 
helps immensely with wired nics (not so much of a problem these days), 
and I believe Luigi Rizzo's work with the linuxulator and drivers is to 
be applauded ten fold. It takes a great deal of time though- I put 
forward the idea when I was still a BSD pup not entirely realising the 
challenges :) Luigi (and his colleagues) has been working hard ever 
since to facilitate the more challenging aspects of multimedia drivers 
(whether or not that had to do with my comments or not, I don't know).
