I have tested this (using a swap partition on another SD card), and the 
following should do the trick.

# dd if=zImage of=/dev/mmcblk0p1 ibs=512 obs=512 seek=177678
# sync

The value for seek is 90971136 / 512.

After thinking about it I think I prefer this over the firmware boot 
option. I'll keep that as my "restore to factory" option.

I do intend to create a new image of the contents of mmcblk0p1 and compare 
that with the original before actually rebooting. That way I can always dd 
the full original image back in place if anything looks corrupted.
