 Indeed the dump reveals an "empty" device:
 
             Device (VID2)
             {
                 Name (_ADR, 0x00020001)
                 Method (_DOS, 1, NotSerialized)
                 {
                 }
   
                 Method (_DOD, 0, NotSerialized)
                 {
                     Return (Package (0x00) {})
                 }
             }
 
 It is unclear how this should be interpreted. Maybe Windows requires such an
 empty node, or maybe not. Maybe this should be taken as an indication that the
 second device is not supported, or maybe not.
 
 As there is not much we can do, I will close this. The error you are seeing
 is entirely harmless as such, but we may silence it in the future or avoid
 attaching acpivga(4) for these "empty" devices.
 
 Thanks for the report,
 
 Jukka.
