+Subject: Note missing module package name
+
+Debian ships different modules in different packages.
+By default qemu ignores the fact that it can not load
+a module, pretending this module never existed.
+Give a useful hint about the package where the module
+in question resides.
+
+This is a hack, but it makes qemu a bit more user-friendly.
