No. The *hardware* disables the PCI device, at which point all reads 
return errors and drivers fall over. The eeepc-laptop driver then hides 
the device because it's no longer there.

Now, it's entirely possible that this behaviour is no longer present on 
the 1005h. That's fine, and it necessitates changing the behaviour of 
the driver. But it's not a reason for removing the functionality 
entirely, because the 700s, 900s and earlier 1000 series *do* require 
that PCI hotplugging be peformed.

(Well. There's a separate situation where the PCI runtime power 
management code is going to interfere with the way eeepc-laptop does 
things, and this functionality is going to need to be added to the PCI 
core and removed from eeepc-laptop)
