MathJax can also (apparently) render MathML on Chrome.

Maybe the answer is:

Write maths notation on your site with MathML. (You'd probably want to preprocess LaTeX notation into MathML some way, because MathML isn't fun to write by hand in the same way that septic tanks aren't fun to unblock by hand.) This will be displayed natively in Safari/Firefox, and be accessible to screen readers (apparently.. I don't use one so don't know what it's like in practice).

Serve MathJax to Chrome users so they can see your maths.
