As I've already told you my testing on the MPC8308RDB board was 
successful. As for 85xx boards, Wolfgang told me that DENX doesn't have 
any 85xx boards that support MSI at the moment, so I can't do complete 
testing. I'm sorry. I've tested that TQM8560 board is able to boot and 
PCI is working as expected though (with your patch applied). I fear I 
can't do anything else here.

Thanks.

Regards, Ilya.
