If it was enabled by MOTLoad (the monitor on the MVME5500), then it has 
a bug similar to RTEMS mvme5500 (arbitrarily limiting number of busses) 
since the bus and device don't show up with pciShow (and other pciFoo) 
commands in MOTLoad, but after increasing the number of busses in the 
RTEMS source it is showing up in RTEMS using BSP_pciFindDevice.

I'm still not sure who enabled the bridge.
