Given that signals on a floppy interface are active-low, I'm going to 
venture that the sequence should be power to the CPU, then power to 
the drive.  This should prevent spurious drive head-loads, accidental 
writes (even if you don't think you'll ever have a disk in the drive) 
and other nicieites.

Similarly, powering down should be drive then CPU.

Or at least that's what seems reasonable.
