Does anyone know of any smartphone projects where the circuits are designed to give the user's OS (usually GNU/Linux, but could be anything the user fancies if the bootloader's free) control over power to the baseband CPU, SIM card processor, and OS on the Wifi card? As far as I know, the Neo900 project is the only one attempting to allow the user's OS to control power to all those other ones.
It doesn't exist. And in the current market, it can't exist.
All the core silicon is wrapped up in huge quantities of NDAs and licensing agreements. You buy a baseband, and the mfg gives you a blob you can either use, or not use the baseband.
