Not entirely sure what your question is. If it's exclusively about
SLI, nouveau presently has no SLI support, nor has there been too much
thought put into how we might support that. No other mesa hardware
driver supports SLI configurations either. Getting reliable reclocking
on nouveau seems like a much bigger potential performance gain than
trying to do SLI. (Although the two are fairly unrelated to one
another, so it's not like one is a prereq of the other.)

That said, the GPUs *should* be supported individually, so if you're
having trouble with that, you should provide more info.
