Minus a couple of obvious typos that prevent if from building, it seems to do the trick for me with the AST driver, no more bad mappings. I'll still send a patch that catches the incorrect mapping attempts inside ttm_io_prot() and warns to help future debugging and avoid "random" behaviour. (I need to fix other things in the powerpc code in there anyway).
