It appears that the ipv6 module is not available at time of activation
of the interface. I cannot reboot the machine to check where exactly in
the boot sequence the interfaces are brought up. 
Try re-creating your initrd after having brought up the sit device. It
could be that some kernel module(s) need to be added to the initrd
