Hotplug PCI has two sides of things :
- drivers and software must support hot plugging : there is support in
  the Linux kernel for that. Digium drivers don't support that yet,
  but this is not very hard to do.
- hardware : you must have hotplug capable boards and bus. I believe
  the only option there is CompactPCI, and of course cPCI boards and
  chassis are very different from your day-to-day PCI stuff. Of course
  Digium boards, as well as any other standard PCI board does not
  fit.
  cPCI boards and chassis are considerably more expensive than their
  standard counterparts, if they exist at all.

You can't just hot (un)plug a standard PCI board : the bus is not
meant for this, you have most chances of destroying your board and/or
your bus.
