Hmmm... thanks for the pointer.

According to the comments in valid_reg() and bios_rd32(), some C51 have this
register misaligned on purpose.

There is something special about the DVI-connector of my GeForce 6150SE nForce
430 (NV4C): it is connected via a Sil1364 sDVO !
The DVI connector currently doesn't work (anyone out there with a datasheet for
the Sil1364 ? ;-) ), so I can't test it. See bug 26797 for details.
No problems with the VGA connector.

I don't know about GeForce 7025 nForce 630a, might be similar ?
