Good point. A quick search on the Internet suggests that 2GB sticks can
be had for < $10. So maybe we should just bite the bullet and target 2GB
keys and do a 1.7GB (1,700,000,000 bytes) image leaving ~300MB free for
the overlay. 

Then leaves both wiggle-room and also enables us to include *compelling*
stuff like Ogg Theora videos featuring Shadowman etc etc.
