Access Points
Several aps are running linux on this chip:
Linksys Wet54gv2: http://www.linksys.com/support/opensourcecode/wet54gv2/2.07/wet54gv2_2.07.tgz
http://www.computex.com.tw/news_archive_detail.asp?index=6378

3Com 3CRWE454G72ME: http://www.3com.com/prod/fr_BE_EMEA/detail.jsp?tab=support&sku=3CRWE454G72
http://www.ovislink.com.tw/wl5404ar.htm : wget http://www.ovislinkcorp.com/DRIVERS/WL5400APb15.img ; strings WL5400APb15.img | grep linux
http://www.sitecom.com/products_info.php?product_id=237&grp_id=6 (with open telnet port in Firmware 1.017
- Others?
Hacking
JTAG
JTAG access? Where is the source code?
Get the firmware of the Siemens wlanap600usb: http://support.fujitsu-siemens.de/DriverCD/Accessories/Files_gepackt/Wireless/02_WLAN/09_connect2AIR_AP-600RP_USB/AP-600RP-USB_FW_7.0.zip
strings firmware | grep Linux
It runs linux but with no source code available!!!
Source is here: http://www.fujitsu-siemens.com/rl/products/wireless/AP-600RP_GNU_source-code.zip
Serial Port
The pinout of 4pins red connector on this picture is on 3.3v, and composed on 2 pins ground and 2 pins in 3.3v. Those 2 pins should be TX and RX, maybe building a connector like this will work.
Source code
* from Linksys :http://www.linksys.com/support/opensourcecode/wet54gv2/2.07/wet54gv2_2.07.tgz ; It's a complete toolchain!

Linux Gaining Support In Embedded Systems (TechWeb) (Posted Dec 11, 2003 19:03 UTC (Thu) by erich) (Post reply) Typical "embedded" Linux systems are kind of "homegrown"... the one i've seen - the SDK of Intersil for the ISL3893, which is - although mostly GPL - NOT publicly available - is based upon a fork of uclinux around late 1998. It sucks. They hacked their logging into every application, disabled features and made many many mistakes (wrong #ifdefs and such) while doing that. Instead of providing proper patches they ship ancient versions... They also did not push back their changes into uclinux, so they could be intergrated into future releases (such as hardware information that uclinux could build out-of-the-box for that hardware) And zcom, taiwanese manufcaturer further modified the kernel without releasing source... Manufacturers suck. They havn't understand Open Source, and that is why they have all these problems.
Why Intersil does not give their modifications to the kernel and BSDL files public?
