I'm afraid things are not as simple as that. Unfortunately you cannot
expect ATAPI drives to properly reject MODE_{SENSE,SELECT}_6 and try the
_10 variants in that case: the reason why ATAPICAM inconditionnally
translates the _6 commands into _10 is because some ATAPI drives have
been found to lock up when they rececive the _6 commands, whereas the
ATAPI specification only mandates the implementation of the _10
versions.

Great! That could also allow the creation of per-track /dev nodes, as
acd has.
