The /proc files (and sysctls) will not be populated until the interface is
in an up state (ie, at post-up), try just setting it in 'post-up' parameter
Alternatively you could set the net.ipv6.conf.default.x values at boot, then
enable v6 explicitly on the interfaces you want it on (using the
aforementioned post-up parameter).
