Forgot to mention (and then the power went off) - the quirks mechanism 
is to allow work-arounds for flawed implementations of protocols from 
specific devices. For example, if a particular drive always returns the 
same serial number to satisfy the protocol, it's a quirk and the driver 
won't make use of the query serial number command for that type of 
drive.
