--- Comment #26 from Ilia Mirkin <imirkin at alum.mit.edu> ---
FTR, the _ROM function from both dumps (same thing):

            Method (_ROM, 2, NotSerialized)  // _ROM: Read-Only Memory
            {
                Local0 += Arg0 = (VRMB (0x04) + Local0)
                Local1 = (VRMS () - 0x04)
                If ((Arg0 < Local1))
                {
                    OperationRegion (OROM, SystemMemory, Local0, 0x1000)
                    Field (OROM, AnyAcc, NoLock, Preserve)
                    {
                        R4KB,   32768
                    }

                    Return (R4KB) /* \_SB_.PCI0.PEGP.DGFX._ROM.R4KB */
                }
                Else
                {
                    Local0 = Buffer (0x01)
                        {
                             0x00                                            
/* . */
                        }
                    Return (Local0)
                }
            }
