Unfortunately the patch does not work fully as expected.
It worked on the machines it was tested on originally, but those
had both SCSI disks as well as SCSI CDROMs. It looks as if 
/proc/devices lists the device driver entry only for device
classes of which at least one device is attached.
So if e.g. the SCSI CDROM driver is compiled in but no SCSI
CDROM is attached, sr is not listed in /proc/devices.

Therefore the patch is not really suitable to solve the problem.
