9	  Say Y here if you have a motherboard with a PCI Hotplug controller.
10	  This allows you to add and remove PCI cards while the machine is
11	  powered up and running.

21	tristate "Fake PCI Hotplug driver"
22	help
23	  Say Y here if you want to use the fake PCI hotplug driver. It can
24	  be used to simulate PCI hotplug events if even if your system is
25	  not PCI hotplug capable.
26
27	  This driver will "emulate" removing PCI devices from the system.
28	  If the "power" file is written to with "0" then the specified PCI
29	  device will be completely removed from the kernel.
30
31	  WARNING, this does NOT turn off the power to the PCI device.
32	  This is a "logical" removal, not a physical or electrical
33	  removal.
34
35	  Use this module at your own risk.  You have been warned!
