Can you check whether your renderd is actually retrieving render 
requests from the module (does it kick into action when you access a 
tile? perhaps try starting with -f from a console).

If no, this is your problem. If mod_tile doesn't log anything then 
strace it to find out what's happening.

If yes, are you sure taht renderd writes tiles to disk *and* writes them 
where mod_tile expects them? Again, strace will tell you where mod_tile 
expects them. Are you positive that renderd/mod_tile are both compiled 
with metatile support? It has been the default for as long as I can 
think but you never know.
