Mmmm.. yes, the "BLANK" opcode is indeed the same as ATA_12.

Yup, BLANK is commonly used with CD-RW software (cdrecord, k3b, ..),
so we cannot translate ATA_12 for ATAPI CD devices.

How about a hack to the upper layer (scsi, or block??) to allow ATA_16
even when the max_cmd_len is 12 ??  In reality, the command length is
unimportant in that case, so it's more a matter of tastefulness than anything.
