It's worth noting that Windows didn't support native pcie hotplug until 
Vista, and so any hardware that works with XP (ie, basically all of it, 
including Dells) is supposed to be using acpi hotplug instead. I've 
fixed one bug that led to acpiphp not working on some hardware, but if 
anyone's still running with pciehp_force=1 then please send me the 
output of acpidump so it can be fixed properly.
