I believe the Linksys firmware source kit is all you need. It is Open=20

know the sveasoft firmware is close eough to a standard linux to support=20

port. The current kernel is according to the makefile a 2.4.20, the Busybox=

version is 0.60.0 according to the Changelog. It uses uClibc so I guess=20
changing/adding functionality should not be that hard. The code for the=20
broadcom wireless stuff is object-only though.
