[WIN32K]
- Since some display drivers don't do as they should - return the drisplay driver name in the DEVMODE's dmDisplayName field - but return the miniport driver name, fix that name when creating the mode list. This fixes loading of VBox driver, when it is installed properly, which needs to be fixed as well.
