It probably wouldn't hurt to ask, but don't get your hopes up. TI have little 
to gain, and a release will cost them at least the time taken to ensure they 
are allowed to release the information. They may not be allowed to release it, 
even if they wanted to, for a number of reasons including third party rights 
holders and regulatory rules.

A good chunk of the code in that area is a binary blob even to Openmoko, which 
is one of the reasons the problem was difficult to debug in the first place. 
You are asking for more access than even Openmoko had.

I think you stand a better chance of getting the Glamo opened than the 
Calypso! I assume you would like Atheros to open the WLAN firmware too.
