That seems like a driver problem.  Does lspci show your devices  
after
you boot?  Also, what kernel ver are you using?

No, the device behind the bridge is not recognized, although the  
bridge
itself is. I am using kernel 2.6.15.

I am trying to use a PCI-X bridge (Intel 31154) on a mpc8540ads  
running kernel
2.6.15.  A USB controller is behind the bridge.

When the mpc8540ads is booted with the PCI-X switch disabled, the  
device
behind the bridge is detected (and actually works), and the following
messages are printed:

Are you using a Rev A or higher board?  PCI-X doesn't work on earlier  
systems.

Also, make sure your board is configured to run PCI at 66 MHz.  PCI-X  
doesn't work at 33 MHz.
