OK, I guess it is time to post what I have.  This is kinda, sorta running.

Unless you make a few changes in arch/ppc/kernel, including creating
some 8240 specific start up functions, it won't matter where you
place the First Instruction :-).

No, this works fine with a PCI Ethernet card.

Since the 8240/Sandpoint has such a small flash rom, it is your
only choice.  There isn't room to store a Linux kernel or compressed
ram disk.  You have to download the kernel over the serial port and
use diskless NFS.  Even though it has a standard IDE and floppy
interface, there are no provisions in Dink to load an image from
these.......Guess it is time to write yet another Linux flash rom.
