mangoo: Your approach to debian looks very interesting, since I am currently building my WL-500gx with OpenWrt Kamikaze 2.6 kernel, and there are some problems with it...

Does debian on a 2.6 kernel support the bcm43xx driver? Is it working?
Compared to OpenWrt: http://forum.openwrt.org/viewtopic.php?id=7842

If everything is stable with debian, I'd switch immediatly :-)
