I have a similar problem: when I start X, it defaults to clone mode but 
my secondary monitor remains blank. Playing with xrandr doesn't fix it.

Running X with the nv driver beforehand helps though: I get both heads 
working, and then if I restart X it works with nouveau as well.

Unfortunately I can't test fixes at the moment, or only against the 
driver as it was in May 7th (because I'm not tracking Mesa or DRM 
repositories atm).

I hope this helps anyway,
