[xmonad] telling xmonad that apparently huge screen == 2 screens

Hi. Have a look at:

That one should work fine for you, unless you have a third screen that
is detected correctly. For that scenario it i possible to make it work
also, but not so nicely.

It will work for all apps that are managed by xmonad, but some other
may still misbehave. For example if you try to use dmenu with the
xinerama patch, I think it will try to use both screens as one single.
Since it is only xmonad that is aware of your split.

Maybe I should actually start commiting all those changes I made...
Since that is one of them, allowing you to make the split on the
current screen, and not all screens.

Good luck.
