Yes, the ioctls will allow you to change the fb size, thus implicitly
change the associated overlays' input_size. There's a nice cmd line 
utility (fbset) to do this (which is not packaged but I plan to do), 
and we've been toying with this for emus (see IRC).

Unfortunately, I doubt you can change the SGX framebuffer size without
restarting the SGX or crashing hildon-desktop at least. So this is 
limited to programs that have the extra framebuffer device in mind.
