Back to my previous attempt then which seemed a little less elegant: the 
idea was that I would initially register the pointer as relative but 
check in the first call to xenfb_mouse_event() and if I had guessed 
wrong, remove the existing mouse handler and add a new one with 
registered as absolute.  If the mouse turns out to be absolute, we miss 
the very first pointer event but this doesn't seem to be much of an 
issue because everything will be sorted out on the next mouse event (the 
various pieces of code that are interested in whether or not the mouse 
is enabled seem to be OK about switching from relative to absolute).
Before I commit a patch to electrons are the any obvious flaws in that 
approach?
