I'm generally concerned about events which don't work well in other media. One of the challenges we faced while developing the n900 was dealing with web sites which expected a fully functional two button mouse (the n900 is a touch screen with no buttons). We've had designs at time which provide for showing a mouse on part of the screen and enabling a user to tap on the left/right buttons etc., this is painful, expensive, awkward, and I don't have any studies showing users manage to make this work. Having to deal w/ the scroll wheel case makes this worse. Otoh, it /might/ be ok to specify "onzoom" and "onscroll", most devices have /some/ support for these operations (in the n900 we have hardware volume keys which are sometimes used for zooming, and the user can user their finger or stylus to trigger a scroll operation). The same general behaviors could exist in e.g. the iPod Touch/iPhone/iPad -- none of which have a scroll wheel. Sorry for the lateness of my reply, I was on vacation last month and now have 100+ conversations in this group to catch up on (this includes not being able to respond to messages between "LC Announcement" and "LC Deadline").
