Sorry to hear this particularly bad news! I wonder if anyone lurking around
the Pyra community might be able to bring some expertise to the matter. I
noticed that certain technical issues, albeit in a different area, were
greatly assisted by people with access to tools and knowledge through their
workplaces or professional situations. Maybe some of those people, or others,
might have something to share about this.

Yes, this doesn't make me very comfortable about Neo900. Then again, maybe
someone involved there can figure this out and bring their experiences back to
Personally, I think some flexibility about the SoC would be acceptable for
Neo900, but I'm not invested in Maemo at all and have backed that project
because of the form factor, open hardware aspects, and Free Software support.

On the topic of lucrative products, I guess you'll be selling the Letux 15
board that the Pyra uses as its CPU board, will you not?
