Please make it work :)

There's nothing conceptually wrong with being able to do:

        echo ":Model:Flags" > /proc/scsi/device_info

We keep running into issues where the same device needs to be listed
many times because it gets branded by different vendors.

Brownie points for making all this less clunky. The libata globbing
blacklist works much better, fwiw.
