I found the difference - in 2.6.28 the inbound/outbound windows

'fsl_add_bridge'
was common among architectures and ended up calling 'setup_pci_atmu'
which created those mappings.  In 2.6.28, the 83xx PCI setup code
has been refactored.  It uses 'mpc83xx_add_bridge' instead of
'fsl_add_bridge' and 'setup_pci_atmu' is not called at all :-(

I'm sure this is the problem.

Looking at a diff between 2.6.26 and .28 I don't see the 83xx pci code  
calling setup_pci_atmu().
