The buttons and many other things are unstable or do not work with a 2.6 Kernel. If you simply press any button tested on a Fonera on a WL-500G Deluxe and a WL-500G Premium the system halts (checked with a serial console). That's it. Said many time to the core developers but it seems the brcm47xx-2.6 target has more other important things to fix first.
I'm back to use a 2.4 Kernel and the buttons do work perfectly...
