Just don't bother with displaying crucial data on hover, think of
people who don't use a mouse, or those who may want to copy and paste
some of the data.

Display the data for javascript off and collapse it when JS is
available showing and hiding it with an onclick handler to allow for
mouse and keyboard access - and all are happy.
