OpenWRT will run IPv6 fine; Comcast posted patches some months back to 
enable some 6rd configuration mods needed for Comcast's IPv6 trial. 
 From the  Comcast beta forum, it's clear that some people have 
succeeded at merging those 6rd patches into OpenWRT, though there may be 
some rough edges.

I haven't had time to take them for a spin.
