Hmmm....this is in 2.4?  Did you apply all of the 36-bit IO
patch as Pete Popov has mentioned in past e-mail messages?
Did you make sure you enabled CONFIG_64BIT_PHYS_ADDR?

I know this does work.  In fact, you should just use
io_remap_page_range().  If that doesn't work, something
is wrong with the kernel configuration.
