In the changelog, you can find that the 'evdev' patch has been included:
* Tue Jul 04 2006 Gustavo Pichorim Boiko <..mail@removed..>
+ 2006-07-03 11:05:06 (38323)
- Removed the FIXME lines. All fixed.
- Added a patch providing evdev support for the Xephyr kdrive server. It is used
for multihead/multiseat solutions
So, I now have an additional TO DO in my pending tasks: Test if a multiterminal configuration can be obtained using a standard distribution without additional external packages or patches. Maybe Mandriva 2007 will be the first affirmative answer.
