ndiswrapper

We need to put together a  HOWTO for using ndiswrapper.  Anyone who buys 
a relatively new laptop will likely get the latest wireless cards 
builtin, and ones like my broadcom card have no linux drivers, nor are 
they likely to end up with some anytime soon. 

Not that ndiswrapper is all that difficult to use, but if we've got all 
the info in one place, it's MUCH easier.
