Wouldnt it be just easier to do it the debian way inside SB.

1. get the list of packages right so the dependencies are met.
2. If you need to modify or add some components then have them available
in a different local repo [building, packaging and resolving their
dependencies is a step that should be done seperately, possibly in
another SB maemo rootstrap]
3. for nokia 770 add the magic packages from nokia binary distribution

and you have your new rootfs for nokia 770.

For other devices, to use maemo, you would have to provide device
specific stuff. Or even better to get the reverse dependencies on what
packages depend on packages provided by nokia, and approximate what in
functionality they would mean for the different device, and have
packages (dummy or providing similar functionality but for your device
like device state management, battery management, input methods and VKB etc)

Then comes the desktop part etc, which is hildon, remove all af-desktop
related components from your build as hildon is  quite n770 800x480
resolution tied. See what could be used from e.g GPE etc package them as
debian [that could be quite a work]

Also lot of device startup procedure would have to be streamlined

would be quite lot of work but IMHO doable :) Just IN MY PERSONAL
OPINION, it would great to see option of 2 toolkits (GPE , Hildon), a
core base maemo platform + adaptation layers , and device specific
layer, and common set of development tools and environment [SB etc, with
different toolkits etc]
