Hi, I just came across this patch: posted it back in December but didn't get any feedback, unfortunately.
I'm using it on two of these boxes and know of some others too. Haven't checked whether it still applies to current trunk, though. link to patchwork: <http://patchwork.openwrt.org/patch/1689/> Please give some feedback on whether or how it can be merged into openwrt.
