Ok, based on the information I've found there, it looks like I can do
the following to get back to factory default flash contents
(reference: http://wiki.laptop.org/go/Autoreinstallation_image#Manual_downgrade):

copy-nand d:\boot\os650.img

This is done at the OK prompt (presumably booting off a USB device)
and d:\boot\os650.img is the os650.img file found at:

http://download.laptop.org/xo-1/os/official/650/jffs2/os650.img

Am I correct in saying that this will return my G1G1 laptop to the
factory default flash contents?
