[Nouveau] nvs280 / nv34 card only does 1680x1050, not 1920x1080 ?

[Hans de Goede]

Hi All,

I've recently acquired a nvs280 card, which is a nv34
gpu based card with a pci-e bridge on the card, this
way I can test nv3x problems without needing an agp
motherboard.

One thing which stands out with this card is that
it drivers my dvi lcd monitor at 1680x1050 instead of its
native 1920x1080.

Is this due to a known limitation on the display pipeline
of these cards / nv34 gpu-s. Or is this more likely a bug
somewhere ?

Regards,

Hans
