That's right, there's no direct way to embed maths in Haddock. It has
been a somewhat requested feature for Haddock over summer when I did
work on it but it didn't make it in.

If you want manually-written LaTeX, this is probably the only way at the
moment. If all you want is some LaTeX snippets (maths), your best bet is
to probably write those separately, make images out of them and then
embed them into your documentation. There's currently no way for Haddock
to do this for you. We do however have a LaTeX back-end so it's not like
it's impossible to generate but it'd require some work that has not yet
been put in.
