All this is great news!

I'm going to pick up a spare 8GB card.

PB, please tell me if this makes sense:

1) install Diablo.
2) run your tool to regenerate the bootmenu.

I then have an n810 that can boot to Diablo (from flash) or Chinook (from mmc1)

3) Put the spare SD in.
4) Clone

I then have Diablo on the spare mmc1. This lets me test Diablo; if I need to, I can revert to Chinook by swapping SD. My flash remains my "safe boot in case I brick my other parts".

Somehow, I also need to fit KDE and the full maemo sdk into this - I need to be able to compile stuff.

?
