The problem is you didn't export acpiphp_check_host_bridge.  And I think
you would have to remove the module_exit function from acpiphp rather
than just clearing that pointer and hoping no-one called through it
recently.

Alternately, Greg could just cherry-pick commit 
6037a803b05eef9943fb64982e19964007fb7478 'PCI: acpiphp: Convert acpiphp
to be builtin only, not modular'.  acpiphp was never very useful as a
module since it didn't get auto-loaded.
