Okay, so I attempted to ressurect it. Anyway, here's a patch that
checks the vendor/model/rev of scsi devices to see if it's the
diskonkey. This specifically only checks for rev 2.01 since that's what
I have and I don't know if other ones have the same problem or not.
Also, I've never written anything for the kernel before so I'm sure this
is better put somewhere else, but it works either way.
Thanks,
Jeff
