It's not currently possible with the current nv driver.  I think there
may be enough information in the nv driver to add dualhead support
(shouldn't be too hard since I think there is code to set modes on both
crtcs, you just need to add the proper odds and ends to use them both
at the same time), it's just that no one has done it yet since nvidia
provides support for it in their binary driver.
