Set it up so you suspend it, instead of turning off. Unsuspend
is much faster than boot.

I wonder: For such a simple setup, could unsuspend be used
instead of booting? I.e. if you lost power, you unsuspend into some 
saved image, instead of waiting for a cold boot.

To be completely power-proof, use a synchronously mounted sdcard. Slow 
fs, but gps logging is low volume anyway.
