Hi,
I'm trying to get pci-express hotplug working in a box here. I don't
really care about the hotplug aspect, I just want the darn pci-e slots
that are designated hotplug slots to actually WORK. When I load pciehp,
I get:

pciehp: PCI Express Hot Plug Controller Driver version: 0.4
and the devices in the hotplug slots stay off. Is this an ACPI/bios
issue? How can I debug this?
Can you try the acpiphp driver instead? That's usually the driver you
want to use for "modern" systems (i.e. anything made in the past 5
years.)
I should have mentioned that I tried that too. It doesn't complain, but
I don't see my cards anywhere afterwards. I'm a hotplug newbie, do I
need to do anything else?
Tried this yet:
options pciehp pciehp_force=1
??
