If you are sure that you can build kernel for that modem device then try 
it. From my experience it's rather hard. Mainly because today's hw is 
too cheap to have working hw interfaces(like DSL modem) and it's all 
done in software way.
Shortest and fastest way would be setting this modem as transparent 
bridge. Then put your own router/gateway(which is IPv6 capable). Router 
on WAN side connects through PPPoE to your ISP and LAN/WLAN side 
connects to your switch or you computers directly. It will be additional 
device between you and your ISP but in many cases that's much better 
than having all-in-one(which can't do IPv6). I'd go that way.

I hope that puts more light to what you try to do.
