Nvidia 6150 with 6600 or 6800 on PCI-e x16?

[PeterAlt]

Does anyone know whether or not the addition of a 6600 or 6800 GPU to a 6150 motherboard will work with the 6150 integrated graphics, like SLI, or would the two have independent displays (like ATI is claiming with their x200), or would the added GPU simply cancel out the onboard GPU?

It would work in addition. No SLi.
