mouse tilt wheel firefox horizontal scroll

This is generic ubuntu (linux,,even) not just crunchbang, but I have a mouse with a tilt-wheel which should be used for horizontal scrolling.
There are a whole load of hits iin google about getting this working, a typical example is here: http://beranger.org/index.php?article=1137&page=3k
They seem to work fine, horizontal scrolling works for me in #! 9.04.

But there is nowhere that describes what the possible setting for firefox horizscroll.withnokey.action can be, or indeed what any of it means.
I've done a quick test, and it seems to be:

0 horizontal scroll the page
1 big-step horizontal scroll, perhaps even horizontal equivalent of "home" and "end"?
2 back, forward in the history - with my mouse the sense is reversed, ie left tilt goes forward, right-tilt back
3 zoom-in, zoom-out
4 tiny-step horizontal scroll

Since there are very few web pages that need horizontal scroll these days, I'd like the tilt wheel to work as "home" and "end" keys, ie scroll to the top and bottom of a page.  I'd prefer not to run a mouse/keyboard remapper daemon (eg btnx) if possible.  Does anyone have mozilla code and can report what the possible actions are, or is there a good way to get this working?
