There seems to be some magic force linked to this mailing list. Whenever I post a question, the matter seems to resolve itself. :)
In order to stay as consistent as possible with the old 2.4 kernel, I used the same mapping that they had: 0x50000000 - 0x6000000000 for memory 0x60000000 - 0x6100000000 for I/O When I changed it to the default that was in the lite5200b device tree I could access the memory regions as well. Thanks for your help!
