    acpiphp: disable bridges
    
    Currently acpiphp calls pci_enable_device() against all
    hot-added bridges, but acpiphp does not call pci_disable_device()
    against them in hot-remove. So ioapic hot-remove would fail.
    This patch fixes this issue.

Not sure that is it really, it is possible i made a mistake during bisect
(the symptoms changed from bad page to just networking doesn't work
somewhere at 4cfee88ad30acc47f02b8b7ba3db8556262dce1e) 

I don't have time to rerun unfortunately
for some time. Anyone else looking would be useful.
