There is some CompactPCI hot swap controller code that was written by MontaVista, but isn't in the main kernel tree right now. I was talking with the author of it to move their code into the existing pci hotplug structure that is in the kernel, but haven't heard back from them for a while.
However, I don't think anyone has looked at device naming based on PCI physical slots yet. I know some attempts have been done for physical location in the USB tree, so some of that old code might be helpful. The hardest thing you will probably have is getting the physical slot name from your pci driver.
Hope this helps,
