Not sure if I can help much :-).

Since you are doing 32bit programming, may be you could see
arch/x86_64/mm/ioremap.c for a 64bit implementation of ioremap() and
try to identify the difference?

Another path:

Take a look here:

http://patchwork.ozlabs.org/linuxppc/patch?id=13588

The guy is patching the 32bit OS for handling 64bit phys addr PCI support.

Looking at all the changes made - are there any difference between his
and yours, which made yours not working?
