Booting with 3 buttons pressed and the SO-DIMM switch in the default (factory) position with a dd copy of the NAND on an inserted SD card results in a boot. Is it a boot from the SD card?

No idea. It might be. No SD card message comes up at all - I've always had *some* SD card message come up when a card has been inserted and three buttons are pressed. I'll try deleting one or two of the partitions on the SD card and see what happens when I try the process again.

Switching the SO-DIMM switch just leaves my system unbootable regardless of what is in the SD card slot.
