The below patch is needed to support ATAPI MO drives in 2.6. ide-scsi
doesn't work any more for this, so ide-cd has to take over the job of
running the MO drive. Without this, there is no way to write to an
ATAPI MO drive.

This patch has been discussed with Linus and Jens already around test9
time and it was agreed this is the right way to go about it. I have
rediffed it against 2.6.0. Compiles, runs, works just fine for me.
