Basically working here, thanks to that nice document. One of my drives
even supports this, so I can easy test the new stuff :-) Patch follows
next days...
But one question remains: what unit should be used for speed selection?
/usr/src/linux/Documentation/cdrom/cdrom-standard.tex mentions *nothing*
(should be fixed). The scsi commands use kbyte/s here (raw, i.e. 176=1x).
This is IMHO ok and we should use that too.
