The page size that the struct wants is the main data area only, not 
counting OOB.  But as Magnus pointed out, you don't need to worry about 
any of this.  It should Just Work(tm).

What does need to be supplied is a controller driver.  There have been 
some patches in the past, but IIRC some more work was needed to get it 
mergeable.
