In the later case, the worry is that the driver will potentially still take shared interrupts after you have disabled the device. I know the normal disable path only disables bus mastering, which is a GOOD thing :-) but the pcibios hook might do more here ... I would recommend only doing that disabling in the "noirq" phase of suspend to avoid problems here. Do you see any reason that wouldn't work ?
