Hi,

This driver does not build upon the previous patch set at all, so I 
didn't mark it as a v2. It is completely rewritten from scratch. I sent 
a note saying that the previous patch set was abandoned. There may be 
some similarities with the previous one, simply because the drivers do 
the same thing, but I don't think there is any need to compare it with 
the old driver I mailed out.

Thanks for your time,
Eddie
