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: http://rhombus-tech.net/evaluated_cpus/ > - GPU2D : Video Processor for hardware 1080p decoding > - RAM 512 Mo > - SSD 8 Go > - Screen 10’1 (WSVGA, 1024x600) > - Capacitive multitouch screen > - Battery 5000 mAh > - HP stéréo > - 4 buttons > Connectivity : > - Wifi B/G/N > - USB > - SD reader > - Ethernet > - Headphone connector 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: http://rhombus-tech.net/community_ideas/kde_tablet/news/ Much closer to the above, at least in terms of the CPU and internals is the following: http://shop.goldelico.com/wiki.php?page=Letux%207004 > We have planned an appointment with the CTO of Unowhy? to see how they > could work with Debian community.

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: http://projects.goldelico.com/p/openphoenux/ 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).
