Offering kernel module packages is rather cumbersome as the kernel modules has 
to match the given kernel _exactly_. I'm not sure how far this goes (some 
tests would be needed) but I'm sure you would need the same sources (including 
all patches, same compiler, may be even binary compability?).

Batman has an internal blackhole detection. The olsr dyn_gw is a hack (its 
just pinging the outside world which works in many cases) - batman has this 
functionality inside. As every traffic flows through the batman tunnel (forth and 
back) batman can "observe" the traffic and detect blackholes (nodes announcing 
internet without a connection) much better. As soon as you generate traffic 
batman will switch the gateway.
