Well, the point is that with KMS on, everything modeset related is
managed in kernel, and not by a userland driver (be it the X one). So
basically, it does improve the situation for console people too (for
example, having a 1400x1050 console is really nice). But I don't really
know how to manage multi-monitor from console, tbh.

I think you don't use it. Could you paste your /proc/fb?

Here (with KMS on) it returns:
cat /proc/fb
0 inteldrmfb
