At least for reading atapicam(4) works on sparc64 and cdrecord
is also known to work for writing CDs with SCSI writers on
sparc64, I currently don't have hardware to test whether it's
also possible to write CDs with ATAPI writers using cdrecord
on sparc64 though. Given that atapicam(4) works for reading
it's unlikely that there are bugs preventing writing, I think
it's way more likely that your drive is one of those incapable
of simulating writes or it denies writing in PIO mode.
