Yep, I've patches in the works to fix this properly, but, with
about 18 outstanding PCMCIA patches against 2.6.0, it's getting
fairly difficult keeping stuff in line.

We basically need to allocate a resource from the bridges parent
resources, not from the root.  This way, if the memory space is not
available to the bridge, it won't be used.
