Just tested your patch on an x86 laptop with two CardBus controllers
(kernel's CardBus bridge code == kernel's PCI-PCI bridge code, for the
most part) and an SMP x86 desktop machine.

The patch worked 100% on my laptop, but failed to allocate a PCI memory
region on my desktop machine.  Two attachments... "diff -u" output for
dmesg before and after your patch, and "diff -u" output for lspci before
and after your patch.
