This patch is very big, especially since the modified qemu files appear 
to already contain support for touchpads. Why is so much code moved 
around? Although we do want this support, we really don't want to 
continue our slide away from qemu mainline at an increasing pace! :-)
Can I apply patches 2 and 3 independent of this one (sounds like patch 
2 depends on 3 to avoid causing excessive CPU overhead, but neither has 
dependence on this patch)?
