its not much help but I have found in general asterisk is not too  
graceful about zap numbering and even starting when the cards in place  
don't match the configuration.

yeah the config is wrong but sometimes there are legitimate reasons  
for that like taking a card out for 5min to try something you should  
be able to still boot the remaining system without it, or add the  
configs before putting the card in. Bigger issue is getting around the  
renumbering of channels when you remove hardware at the "bottom"
