According to this dump, you are not running the latest linuxppc_2_5.
The latest linuxppc_2_5 tree does not relocate memory BARs, only I/O
BARs.  Not to mention the PReP relocation code doesn't properly update
the memory resource limits.

To get linuxppc_2_5:

	bk clone bk://bitkeeper.fsmlabs.com:5005 linuxppc_2_5

If you really think you have the right tree, then email me privately
your prep_pci.c and I'll let you know.
