It is worth noting that the disk spindown code that is disabled for the
FMR does actually work, it just has too many side effects to be practical
on a running box (backlight switches off, power reading unreliable, and
possibly unit poweroffs). This was disabled during the debugging of FMR
boxes early this year. It would be worthwhile looking at using this code
only in this situation on the FMR and see how it works out. We should
still disable the disk poweroff code during normal operations however!
Alternatively, utilise the code that is used when the disk spins down
after a few seconds of user inactivity and after finishing reading mp3
data for playing.
