Why? Why can't it just disconnect the device like the other pci hotplug
drivers do in 2.4?

I really don't like the way the slots are named here, that's why I made
fakephp to only show the existing devices in the system. I'd really
like a change to fakephp that just rescans the pci bus to see if any new
devices have been added by the bios, to handle the "add a new device"
issue. I'll go add a patch to the pci hotplug core to export the sysfs
directory to make this easier to support.
Oh, and this is probably the wrong mailing list for this, there is a pci
hotplug linux mailing list that you might want to post this to (that's
where the other pci hotplug driver authors are.)
thanks,
