I dont think this is necessary.
Let the VDI do its things untouched.
My suspicion is that dev/mouse is never used by a AES at all, but only in
a console to set a text cursor, and perhaps a very long time ago for the last time.
So nobody (but me :) ever had the change to see that there is a little bug
in it.
