Excellent!

Yes, it's an API change, but from what I understand it's only used internally 
in the xserver-repository (ok, evdev have its own proto of it, don't know how 
adding a return value will affect things.. Is it in a bad way?). I only found 
these three hits in all git-repos that Xorg consist of (according to 
source-navigator):

EvdevNew: +336 driver/xf86-input-evdev/src/evdev.c
InitInput: +1023 xserver/hw/xfree86/common/xf86Init.c
NewInputDeviceRequest: +408 xserver/hw/xfree86/common/xf86Xinput.c

Yes, it will break the ABI, but in a 'nice' way.. As long as the two new 
fields are not accessed by the drivers it doesn't matter against what it was 
compiled. The memory is allocated/freed by the server and not by the 
individual drivers. I was kind of hoping we could hook it up with XINPUT 1.0, 
but whether that's possible or not is not something I can tell...

But it's ok for me to push it into a separate branch for the time being.
