I'm not sure what the specs say about how devices should be enabled and disabled so I thought you could give me some insight. The basic problem is that the PnP device needs to be reconfigured after a suspend (since it looses its configuration once the power goes). So I suspect that .set (pnpacpi_set_resources in the ACPI case) should be called upon resume. Should perhaps .disable also be called on suspend?
