FWIW, the attached might help. This is something I added to our 2.4.25 (10-May-04) tree to allow me do the same thing on our '440GP platform. The patch adds a file to arch/ppc/mm that provides an io_remap_page_range64() function, analogous to ioremap64(). drv_mmap.c is the body of the mmap() entry point in my driver for an example.
