Just create a file called /etc/modprobe.d/pciehp,
and stick this one line into it:

options pciehp pciehp_force=1

See if that works.

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.

My Dell works fine with PCIe hotplug under XP,
but not under Linux without pciehp=1.

I have not retested without that parameter for quite some time, though.
What do I have to do to retest with "acpihp" ?
