4331 support

[james at jamesanslow.net]

Hi Larry,

Thanks for getting back to me on this. I'm not overly experienced when  
it comes to driver development and so I may be best suited to waiting  
until this is made live. That is, unless compiling and patching  
experimental drivers is an easy thing to do (but from what I  
understand it's not?)

Kind regards,
James
