Indeed. I do broadly speaking understand how TeX forms pages, and how vertical space can variously be absorbed or stretched. But, preview.sty could somehow communicate (out-of-band) for each mathdisplay the unit the currently valid values of \abovedisplayskip and whatever the other one is called. These would be a decent approximation for LyX's purposes (since LyX doesn't attempt to consider the page breaking algorithm). Jules
