As far as I know that's not possible.
You set me thinking, though. I dislike FIR because of its CSS hackiness,
even though I like the concept. But I suddenly saw what we're doing wrong.
We're using the wrong tool. Our error is that we try to replace text by
images in CSS, while we *should use JavaScript*!
Serve the page with normal text in the headers, then run a script that
*replaces* the text by an image.
This solves all accessibility issues at one stroke. As a bonus you don't
need complicated and potentially hazardous CSS any more, just a few lines of
script and some strategically placed data sources.
Of course we'd lose the few noscript users, but so what? The replacement
isn't essential, it's just a nice extra.
Interesting idea. I'll try to write a script.
(BTW: Is "should we use CSS or JavaScript for this effect" on topic? If not,
the thread should end here)
