Silly, as I suggested a patch to Joerg, it was the uniquely ability to burn
without
ide-scsi. And known you, it simply works, it let me to scan for burners(what
SG_IO cannot), it works
in 2.4.X and 2.6.X.

Make SG_IO better and CDROM_SEND_PACKET will die, without your suggestions.

Alex

P.S. I'm know that CDROM_SEND_PACKET has a overhead, by me it's 4%. I can
live with it.
