Ubuntu Linux - Suggestions needed

Hi Guys,

In ubuntu linux feisty release IPv6 will officially be disabled by default
at this point.  That is unless a solution is found within the next 48 hours
to stop the problem of what they claim as slow fallbacks on non-v6 enabled

So, having discussed this with one of their developers, I said I'd put the
question to this list, what suggestions do we have that will facilitate the

a.) Not impact of fallback / resolution speeds on non-v6 enabled networks,
networks that filter v6 responses, and points where there are cheap dsl
routers that force a timeout on a request of a quad-a record rather than
returning NXDOMAIN
b.) Not force the user to have to answer questions as to whether or not they
want v6 (they say a user mustn't be prompted)
c.) Leave IPv6 enabled by default, or get it to auto-enable on v6 compatible

Any out of the box ideas would be good, cause it kinda sucks that they will
disable by default if no solutions are found.
