Could you send me patches vs. a known kernel tarball, or a link to the
changes you made? Also, what kind of VGA card are you using? I can't
even get my board booted.

I can get it to load kernels to RAM and to FLASH, but I have yet
to build a kernel that doesn't go off into space and crash the board.

I tried loading via DINK... same thing as above. I really think I dont
have a good build yet ;) Also, its TERRIBLY slow compared to the ESTC
loader (since its serial only).

UGH. i was looking for this too: no luck. I will contact mot as well and
see if i cant get some docs from our FAE.

Yes yes that would be a nice feature.
