Andrew -- The use of the word 'hack' didn't trigger any response??

By hardcoding so much of the inquiry data, this patch -overwrites- valid
inquiry data provided by the device, with generic data. This patch
makes generic the probe data that the SCSI layer -depends on to be
different-.

Effectively you made one CD-ROM device work, killed all the others, and
enabled an oops generator.

Good show.

Even if this patch worked, you still need to fix the following:

* Patch INQUIRY data -slightly- to fool the SCSI layer into working
correctly. This is what Andy's patch [poorly] attempts to address.
* Handling DRQ interrupts (early patch exists)
* Padding DMA data (50% patch exists)
* Fix error handling (patch exists)
* Fix all FIS-based drivers so that an error doesn't cause an oops
* Implement non-polled REQUEST SENSE error handling for FIS-based drivers
