this sounded familiar, and i found that i've been using an ugly
workaround for this problem.  it's a filter to pre-process a LaTeX file
(i.e. it's to be applied to a .tex before latex2html): attached.

for a proper solution: latex2html can process \begin{htmlonly} and
\begin{latexonly} sections correctly, so i guess it could easily be
extended to handle comments in general.
