Then your hardware does not support PCI hotplug, so I don't recommend
trying to use it.

Seriously, this is a hardware and BIOS requirement to support this, if
you don't have that hardware, you can't really work around it in the
kernel.  Go buy some real hardware for this please.

Why would there be?  You don't have hardware that notices this.

good luck,
