Yep, I do most ATAPI/CAM develoment on -STABLE machines.

This is being considered, but I am not the one who can make the decision
on this issue. If you'd like to see the code integrated into -CURRENT,
you should let Søren know (sos@freebsd.org).

Well, the ATA driver just reports whatever error condition comes from
the drive. The real solution may involve modifying the SCSI device
drivers (cd/sa/da) so that they do not send commands that may not
work with specific targets, or filtering requests to translate them
into the restricted command set that ATAPI units support (this is
done in an ad hoc fasion in atapi-cam currently, but there is also
work in progress for a general command filtering framework in -CURRENT).
Thomas.
