On guest side the module exists but currently isn't loaded automatically. So the driver fails to be probed and does not its job of handling guest panic events. Instead of requiring manual modprobe, let's include a device database using the MODULE_DEVICE_TABLE macro and let the module auto-load when the guest gets exposed with such a pvpanic-pci device.
