You can buy systems with hot-plugable standard PCI slots.  Many 
higher-end servers have included the ability for years.

If you read down far enough, it mentions that the PCI-X slots are 
hot-pluggable.  Linux has kernel support for the HP/COMPAQ/IBM hot-plug 
chips, but I'm pretty sure that you still need a bit of driver support.
