The board has not many differences with the wl-520gu, small ram (16 MiB), small processor (mips 256 MHz), one usb 1.1, and a b43 minipci wifi with opensource drivers ( it works quite fine in latest trunks).
For getting it work i used this schematic for the IR receiver:

Probably you don't need to solder the mic input ground, because the usb is already grounded to it and shares the ground with the board, I didn't and it works. Consequently you only need to solder one wire to the usb card. Or if you prefer make an external receiver to plug it with a stereo jack, I did it the first time for testing, but I don like stuff hanging on the board, so finally i fitted it inside my router.
The second thing is to prepare the lirc package. Unfortunatelly the receiver type is hardcoded into the makefile package, and in the trunk I'm using there are some lost utilities, I fixed it, this is the makefile and my files for the lirc package (located under trunk/feeds/packages/utils/lirc/) , it includes my remote keys, and irexec commands for the remote.

Because the new mpd is fat as a cow, and my board has little resources, I ported and striped mpd 0.13.2 to this trunk I'm using. (trunk/feeds/packages/sound/mpd/)

Finally I compiled unselecting stuff I don't need (ie: I dont need ssh or iptables..). You know mpd is a RAM eater, little kernels, and elimiating daemons will give you more available ram.
Ok for making the receiver work first lets launch the lircd:
Code: Select all
lircd --driver=audio_alsa -d plughw@12000
Code: Select all
amixer set Mic capture 62%
Code: Select all
irexec --daemon /etc/wifiradio/lircrc
and this is the result
I can provide more details if someone interested
