Hmmm. I've checked 
ftp://download.nvidia.com/XFree86/Linux-x86_64/304.60/README/xconfigoptions.html, 
but not really found anything that seems to be related to this. Also, 
the problem is not really making the monitor the primary, but rather to 
make sure it stays enabled. In a sense, it is a "disabled primary" once 
I log in.

That would be an issue related to the "EDID" monitor info, I suppose. 
But in my case, the monitor is recognised just fine, it's just that it's 
switched off in the driver's internal config. Or that's what it looks 
like, anyway.
