That's not true. I'm currently using 2 1080p screens on a HD7870. You just have to initially set it up using amdcccle or maybe aticonfig, or to edit xorg.conf manually, after which you can use RandR-based tools as normal. I dislike that the AMD drivers lag behind in software compatibility and that they do things in non-standard ways, but they provide all the functionality I'd expect.
Getting back to your problem, in amdcccle set up Display Manager > Multy-Display, or manually in xorg.conf, Section "Screen", SubSection "Display" needs to have an entry called 'Virtual', which looks something like this: Virtual 3840 1920.

I figured you could manually fight with the xorg.conf (which I did last time I had a non-intel card years ago), but by that stage, I'd already spent heaps of time fighting with the card, and it was a work machine and I wanted to get work done. I just wanted to dual-screen Cinnamon, and the free driver did that with software rendering... with my quad-core pegged to 70%. But I live in the console, so I don't notice it except when I open htop - it was deemed 'good enough'. In any case, the AMD drivers, at the current time, require stupid shennanigans to go beyond basics and the nvidia ones don't. The domain knowledge you need is quite high, and the target shifts so rapidly that the search engines are filled with out-of-date cruft. Thanks for the info, by the way - I do appreciate it, but there is already a replacement card coming...
