I would just as quickly assume that the gsm firmware is binary-only.
The update utility (a.k.a. flashing tool) is apparently freely
downloadable, but I have no idea if it's open source.

The 3D is definitely binary, but binary is better than nothing. Still
TI has a pretty decent track-record for playing well with the Open
Source community, so support for the binary-only drivers (and maybe an
open-source one) is likely to continue for the foreseeable future. The
3D is provided by Imagination (PowerVR), and with all of the OMAP
Linux devices that are coming out of the woodworks these days (e.g.
OpenPandora, BeagleBoard, TouchBook, smartbooks), who knows, they
might end up caving and providing some more slack.

I can definitely understand that sentiment.

I guess since it's not one of the 'next-gen' SoC's with integrated
baseband, that there would be the baseband processor, RF modem, and
whatever other components they need. Looking at the Beagleboard though
(p 38 of the ref. manual), it doesn't seem to require much more than
the TWL4030 and a VBAT regulator, aside from passive SMT components.
It has a level shifter for RS232, but that's typical. The USB OTG PHY
is contained within the 4030.
