Yes, same here. The behavior Nigel sees on Archlinux is quite certainly the 
default behavior of X.

I would rather assume that Fedora and "Nigel's Debian" :) did something 

It is also not related to Konsole, any shell either in a terminal window or on 
one of Linux's virtual consoles will do.
The only difference is that in a terminal window like Konsole, a simple su 
will usually keep the environment of the shell, in this case the DISPLAY 
variable "pointing" to the X session the terminal window is hosted in.
