If it works with the 2D FOSS 'nv' driver, we can suggest that to new users. Not much exists in Linux that requires 3D capabilities, so unless new users truly need that, nv should work until this is sorted out.
Unfortunately, I don't have any nvidia cards (I try to avoid them because of their drivers), so I can't test with any other version of the driver.
Unfortunately nv has been broken for a long time. There is no support for wide screen monitors. Been there done that. :)
The nouveau driver is not available in most distros of recent past. Available in the latest and all bleeding edge distros but not those from a year or two ago. We can't ignore those distros. And there remain more than a few bugs with the nouveau driver.
