Unfortunately, this is a problem that must be solved on the TeX level -
AFAIK, there is no LaTeX package LyX could use to achieve this. (Maybe you
write one or present the idea at comp.text.tex.)
The somewhat related issue of floats floating "upwards" from their input
position (on the top of a page with some text originally before the float
now following it further down the page) can be solved by
\usepackage{flafter}
in the LaTex preamble.
