For example, various virtual keyboard pages use such techniques. Say,
http://www.virtualkeyboard.ws has buttons for entering characters, with
mouseover events that show information about the key.

I assumed the latter. At least it makes sense. And it would make sense,
title attribute. The reason is that although graphic browsers generally
display that value on mouseover by default, the implementations have
oddities that reduce usability: the "tooltip" text is in a
system-dependent font (cannot be styled by the author, cannot be
modified by the user except via system settings), and it may disappear
after some seconds.

Say, http://forums.whatwg.org/bb3/ucp.php?mode=register looks like a
sure case. Or did you mean a form that additionally may have a problem
for 20% of people or less? I guess _every_ form has some potential
problem to _some_ people. The form cited has a "Confirmation of
registration" question. I would expect well over 80% of users to be able
to answer it without difficulties, but I'm afraid there's a
non-ignorable amount of people who might get puzzled by it.

I don't think the problem is theoretical (although it was formulated in
general terms - as this seems natural in a discussion like this). The
answer is, as there is no support worth mentioning yet.
So you have some URLs to real world examples? :-)
