you have chosen openmoko very well for your project. Just a few notes that 
might be interesting for you:

As for good power management - it's given by HW design and linux kernel. You 
can't affect very much from userspace. You can get 4-5 days on one battery 
charge, if the phone is in suspend (PMU+RAM+modem is on, rest if off).

Take a look at http://wiki.openmoko.org/wiki/OpenWRT - they have also very 
minimal userspace (just few megabytes) and nice kernel-like build system.

Btw why X11 for such project? Wouldnt be framebuffer enough?

Anyway good luck with your project, let us know if you have something working.
