Port-arm is normally the correct place for evbarm questions.

This has come up before, I can't remember the precise details, but it's 
something to do with the number of static L2 page tables that are loaded 
into the kernel pmap when the system starts.  You might be able to find an 
answer by searching back through the port-arm archives.

I don't think these are working yet.
