I don't understand why people keep quoting this article like it was
something interesting. It's all perfectly known, those are the basics
of how GSM (and other) modems work. However, not every device
communicates with the modem via shared RAM - and Openmoko/OpenPhoenux
devices don't. Despite of modem being closed blackbox, you'll still be
able to control what it does and what it can do - see:

But answering your question: yes, you'll probably be able to order
Neo900 without modem on board, so you'll be able to solder your own by
yourself or just leave it unpopulated - it's up to you.
