Its a custom chip with bridge functionality...(its not hotplug, but the thought was "if hotplug can add a bridge at a later time, so can an arbitrary module". There's a number of minor problems in how BRIDGE_OTHER is handled (i.e. the first two bars should be filled in like any other bridge, but everything else ignored).
The goal is to add a PCI bus behind the bridge (the bios and the kernel doesn't know about it).
So I'm executing the sequence to add a new bus -- which needs CONFIG_HOTPLUG to export the symbols -- which causes the problem with PPC in the arch dependent part (it works fine on intel platforms).
Looking at the hotplug drivers, it looks like its tied to intel architectures in places...but adding a PCI bus should be a PCI thing...
