You don't seem to modify the batman-adv settings. Could you post the batman-
adv config file, so that we can see whether it fits the rest of your uci 
configuration ?

I'm not sure what this will do. Any reason to set these values ?

With "uci commit" you save these settings permanently which then get loaded at 
boot time. If these settings crash your device it is save to assume that this 
happens with each boot attempt.  :-)

Before you try the next "/etc/init.d/network restart" could you please check 
whether the batman-adv module is loaded (using 'lsmod') and whether any 
interfaces are active (using 'batctl if'). The batman-adv version would be 
also interesting to know (can be found in the system log -> 'logread').
At this point I don't see how a "network restart" is related to batman.

Yes, you will need a corresponding cable and pins on the board to connect it 
to. A WRT54GL probably does not have the pins which means you would need to 
solder it yourself.
