I dug up an Actiontec GT704 that I wanted to get running on OpenWRT.  The wiki lists it as supported since Kamikaze (http://wiki.openwrt.org/toh/actiontec/gt704wg), though states the wireless is a WIP.

I got the Backfire AR7 image flashed and booting, but networking isn't working.  My config is unchanged from the default - eth0 and eth1 are bridged into lan, with dnsmasq providing DHCP to clients.

When connecting a PC, however, I see that eth1 (I think - currently away from box) is receiving traffic (I assume the DHCP requests), but not responding at all (no bytes transmitted, client never gets an IP address).

Any ideas where I should start diagnosing and debugging the problem?

Bonus points - anyone have an idea what needs to happen still to get wireless to work?  I tempted fate by enabling it, and got a lot of error messages spewed out.  I'm not afraid to poke at it, but haven't seen any docs about what needs to be figured out still.
