I folded it all down to two patches.  Unfortunately they don't apply very
well to mainline:

1 out of 4 hunks FAILED -- saving rejects to file drivers/pci/hotplug/acpiphp_core.c.rej
2 out of 3 hunks FAILED -- saving rejects to file drivers/pci/hotplug/acpiphp_ibm.c.rej
1 out of 6 hunks FAILED -- saving rejects to file drivers/pci/hotplug/pciehp_core.c.rej
1 out of 4 hunks FAILED -- saving rejects to file drivers/pci/hotplug/shpchp_core.c.rej
1 out of 5 hunks FAILED -- saving rejects to file include/linux/pci.h.rej

I guess because I reworked everything to fit on Greg's tree(s).

fwiw, http://userweb.kernel.org/~akpm/bh.gz (agains -rc9) contains all of
-mm up to and including pci-hotplug-acpi-pci-slot-detection-driver.patch
and is suitable for review/repair/etc.
