It's a basic principal of UI design that you give the user as many
ways of operating a feature as possible and let them choose.

Having the mousewheel as one of the mechanisms of control is great as
long as it fits the basic metaphor that most people are used for with
mousewheels (mousewheels "scroll" in one sense or another).
Having it as the only mechanism doesn't just assume that the
mousewheel is available (which you are trying to verify here, so that
it is no longer a matter of assumption), but that they are physically
capable of using it (or using it with ease), and that they want to
use it. Which UI people favour is a matter of their physical
abilities, personal preferences, how experienced they are, how busy
they are etc.

Besides which there isn't a way to determine mousewheel availability
anyway. Even if you can determine which drivers are on a machine you
would get false negatives.
