Yes, we have these problems with proprietary GPUs.
With last nvidia beta drivers (304.37) and last KDE (4.9.00) on Ubuntu 12.04 KDE show me a dialog when a monitor is plugged/unplugged, and when click on configure show 'display' window (that is attached).
I don't know what code do it, cuz I don't know about KDE code, but I believe KDE sends a Signal for that event (if not is a good idea open a ticket).
