I just searched my own archive and the sources.redhat and found some info 
regarding the board. In the docs of their eval board, at least in the 
website, they say that it now supports ecos 2.0 and they even seem to have 
some source code allowing developers to use different firmwares.

My main objective is to:
** track my position using GPS
** send it through GSM+GPRS and do some sort of GET or POST
** sleep for some time(hours/days)
** consume as little as possible

Assuming that the port is already done but they don't release the source, only 
a binary to link. 
Can this be done?
Are are my options in terms of other boards? Anyone?
