   Mode page 2A of emulated ATAPI DVD-ROM should have page length 0x14
   like SCSI CD-ROM, rather than 0x12. (Just add two 0-bytes to its end
   and adkust the size dependent fields.)

   MODE SENSE(6) should be thrown out of ATAPI DVD-ROM emulation.
   Its implementation is wrong. It is not specified in the ATAPI list
   of MMC-2. MMC-5 prescribes to use MODE SENSE(10).

These done too, will send patches tomorrow.
