I have been able to get root on this router via Ethernet cabled telnet... and I have confirmed it has some OpenWRT origins:

It obvious has customized netgear software.  My question is... can I put it on a "stock" OpenWRT firmware, and what do I need to do to go about that? Or has the changes by netgear not made their way back into the OpenWRT project?

Thanks.
