Their website speaks of +/- 3mm precision, and their user-forum includes
85mm as being the next-most-desired focal length for the pre-programmed
chips, and they have announced 29/35/84/100/135/180mm as being the next
release of focal lengths (as well as 51mm), supposedly available in the next
couple of weeks, but there is a public holiday coming up, so don't hold your
breath.
They also have some examples of IS on and IS off images using a
preprogrammed 51mm chip, using 50mm and 135mm lenses. If I can find a way
of making them accessible to non-registered non-Russophones, I will do so,
but it may take a few days, as I am travelling at the moment.

Any idea how much precision is required in the focal length? Are, for
example, 85 and 90mm lenses or even 85 and 100mm lenses close enough for the
IS to work properly given some intermediate setting?
