I am trying to disable hot unplug of a device on PCI-PCI bridge without 
removing the capability to hot plug. Will it be enough to disable the following 
lines of code?

+                    method = aml_method("_EJ0", 1, AML_NOTSERIALIZED);
+                    aml_append(method,
+                               aml_call2("PCEJ", aml_name("BSEL"),
+                                         aml_name("_SUN"))
+                        );
+                    aml_append(dev, method);

I have sent a patch. Please provide comments.
