There's supposed to be some code that allows slots to be dynamically
added and removed from running partitions, but I've never tried it
myself.

FWIW, field experience shows that nine out of ten failures are due to 
poorly seated PCI cards. Before you chuck it, you might want to remove
it, make sure there are no iron filings in the slot, and try again.

Let me know how that goes; I'd like to add this to my bag of "real
world" experience with this thing.
