I'm trying to install OpenWRT on this hardware using "Edimax BR-6104K" target profile, since "openwrt-adm5120-br-6104k-squashfs-xmodem.bin" is the only image i can get to boot.
I've got some problem with the flash partitions, and with the IRQ assignment to the atheros miniPCI.
This is the console output:
root@OpenWrt:/# reboot
root@OpenWrt:/# adm5120_wdt: disabling watchdog timer
Restarting system.

Honestly, i don't know where to begin... but i think i can do it with a little help... hint and references are welcome! 
If this thing will work, i promise to write a detailed wiki page!!!
