This is actually the third picture of the hardware that HiRISE took. Comparing three images in the flicker gif below, it really seems that the bright spot at upper right is shifting around. More than likely, what we're looking at is actually light glinting off of some of Beagle 2's solar panels; which panel sends the glint to HiRISE depends on the lighting geometry of each observation.

If that really is light glinting off of deployed solar panels, HiRISE has shown us that Beagle 2 worked. Its entry worked; its parachute worked; its airbag-assisted landing worked; its initial deployments worked, at least partially.

Which is heartbreaking. So close -- and yet, never heard from.
