This is from the ASUS.

The device's ESSID during boot is 'Marvell AP-32', and the Libertas AP-32 and AP-52 design toolkits contain only ports of Linux and eCos to the device, according to Marvell. Considering the device's routing capabilities I'm believe it's running Linux, but I don't have a solid proof yet, unfortunately. The eCos port is intended for the non-router variety of the design.
On the other hand, eCos seems to be GPL, too, although it's possible that the owner dual-licenses it.

Good luck. I'll try to take a look, too.

Rather unrelated, I'm trying to figure out what to do with Elo Touchsystems, they used my HID driver as a base of their own binary-only driver and don't answer to e-mail.

I'll take a look, thanks!
