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). > The code is really good IMHO.

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).
