In fact there isn't.  Parking is handled by the drive itself according to
the APM power management settings; we don't really have a good interface to
control parking more finely than that.  The only other approach to reducing
the number of load cycles would be to reduce the frequency with which Ubuntu
requires *un*parking the drive; that's worth investigating, but is going to
take a while to get to the bottom of and is probably not something we would
change in existing releases via SRU unless the fixes were obvious and
straightforward.
