you can find source code and interesting documentation for Broadcom products including Linksys, Belkin and all others AP with Broadcom chipset. Documentation is located in doc/BCM47XX_Resource_Guide.pd
http://web.belkin.com/support/gpl.asp
Sitecom has also released some sources for 2 AP based on Linux. Thoses sources seem to be partial.
Does Belkin work with openwrt? From the TableOfContents page it seems to be untested.
There are tons of information here: http://wiki.openwrt.org/F5D7230
Thanks. Maybe it is a good idea to add a new column to TableOfHardwares that links to related wiki pages on OpenWrt. I wonder what everybody thinks of it..
Actually, when I revisited the page I realized that the "untested" keyword has already a link to this information. 
Also note cfe.pdf in the same gpl code, the functional spec of CFE.
The discussion might have continued from here.
