I get the impression that reality is closer to your dream than you think.
The GTA04 does not *depend* on PVR GPU to be useable in daily life. It is just that some high-end 3D gimmicks are running slow. See e.g. how Numpty Physics (from Debian) works on the 7004 with no GPU support:

GPS does not need any firmware and provides NMEA on a /dev/tty.
GSM/UMTS has an open driver ("HSO") and otherwise uses AT commands, i.e. everything free and open.
The only problematic part is the WLAN chip requiring a binary BLOB. If someone can do without WLAN, it is free and open as well. Or we need people working on reverse engineering of the BLOB. Maybe the recently opened code from Atheros  may give some insights how a WiFi stack works.
BTW, we still have some GTA04 boards at reduced price where the WLAN chip does not respond at all. All other features are tested to be ok.
