Have you evaluated other processors? The PowerVR hardware is apparently
particularly problematic, although people are apparently making progress on
reverse-engineered Free Software drivers. The following page is probably
useful to see which CPUs are the most viable from a Free Software point of
view:

I might also suggest that you look at what the Rhombus Tech people are doing
with their tablet for KDE developers, even though they are using a smaller
screen:

Much closer to the above, at least in terms of the CPU and internals is the
following:

Again, I'd suggest looking at the project making this last product because
they appear to use Debian already and have experience with the OMAP products:

I hope that these links might give you a few ideas. There are many people
doing hardware for Free Software, and also people deploying Debian and
Emdebian on that hardware [*], and it might save time and effort to find
those people and work with them (or get them to help you).
