Hello Felix,
I had a problem similar to this on the 440GX, the PCI code was not
sending type 1 transactions when scanning behind bridges. Perhaps you
could try this:

I think you patch is a valid one, and should be applied, but 
unfortunately it doesn't fix by problem.
BTW, in u-boot transaction type bit is set correctly.
