Another objection, now that I think about it, is that some people didn't 
like the way I made OFW coexist within Linux's virtual address space by 
injecting a page directory entry at the top of one of Linux's page 
tables.  Admittedly, the solution that I chose is rather brute force, 
but empirically it seems to work quite well in the OLPC context.
