You are using a broken kernel tree that relocates PReP memory BARs. I have already fixed this in the latest linuxppc_2_5 tree. Note the large PCI mem space it is attempting to allocate on the line before each resource allocation error message. The >768MB area it's trying to allocate is the clue that something's wrong.
It's generally good practice to try the PPC development trees before reporting PPC kernel bugs. http://www.fsmlabs.com/linuxppcbk.html
