okay, I know here is the focos for open / free baseband implementation,
first for the Calypso chipset.
I have collected some more links about application proessor / nokia
smartphones today. I hope these do not disturb so much.

Linux on N70

"OMAP 1710 has Locosto/Calypso secure ROM"
"All Nokia’s registers are re-mapped from orig OMAP specs.. Nokia did it
on purpose as special order to Texas Instruments. So we will have to blind-probe the memory addresses to find out all
those right addressings.. As well as by disassembling current ARM apps."
"kernel-mode source available to play with!"

"You have no control over it, and the only way to determine it is by
examining the system source code to see how the manufacturer did it
(unless you have access to a low-level debugger that can tell you
what's going on in the device)." => open source symbian

"Cellular Baseband Services Guide"
http://developer.symbian.org/main/documentation/reference/s%5E3/doc_source/guide/Telephony/index.html
=> Baseband Channel Adaptor (BCA) Framework, Inter System Commmunications
(ISC)

but when you search about the Inter System Communications you only found
"restricted access" pages - only for members of Symbian Foundation.

interesting - an other project by Harald, which I do not noticed before:
http://openezx.org/
"The OpenEZX project tries to gather information about the Linux-based
Motorola EZX phone platform (mainly the A780, E680 and E680i phones)."
and there I found sledge with this N70 project:
