Now I try to access the devices on bus 1. I can read the configuration
space no problem, but get bus error if I read the pci memory space.
Checking everything obvious, I see that the the command register of
the pci-pci bridge does not have the memory or I/O space bits set.
Setting these bits eliminates the bus error.

I have now discovered that the same bits were not set for the devices
on bus 1. I am now reading reasonable values from the device :-)

I still need to know where these bits should be setup.
