OK, just correct me if I get this wrong, but this code is taking the LAST 2
characters of the device name and verifying that it is "cd". Which would
mean that the standard states that "/dev/ginsucd" would be a CD-ROM drive?

That is why I feel a "name" of a device handle shouldnt set how a driver
operates in this fashion... if you make a small error in your compare, you
might try to eject a Ginsu Cabbage Dicer instead of a cdrom drive... OOPS!

Actually, no, because it's guaranteed that a trailing "/cd" is a
CD-ROM. That's the standard.
