BTW, I have with acpiphp on 3.7.4:

ls -la /sys/bus/pci_express/devices
total 0
drwxr-xr-x 2 root root 0 Jan 28 13:07 .
drwxr-xr-x 4 root root 0 Jan 28 13:07 ..
$ ls -la /sys/bus/pci/devices/slots
ls: cannot access /sys/bus/pci/devices/slots: No such file or directory
$

And for me hotplug also works (as far as I can tell). ;-)

Would be fine if you could re-do the PresDet checks and confirm whether it is also broken
for you under pciehp.
