Thanks.  I asked about this upstream, and got the following answer:
22:22 < jcristau> btw, i got a bug report about mouse buttons that 'stopped 
                  working' when upgrading from evdev 1.2 to 2.0.x, because 
                  they're reported as 8 and 9 instead of 6 and 7
22:23 < ajax> jcristau: sigh.  buttons-as-axes was such a bad idea.
22:24 < jcristau> should i tell the reporter to use xmodmap, or is that fixable 
                  somehow?
22:26 < ajax> jcristau: xmodmap probably the right plan
22:26 < ajax> at least as a workaround

So it seems you'll have to run something like:
xmodmap -e "pointer = 1 2 3 4 5 8 9 6 7"
(adjust to get the right number of buttons) to make your side buttons
report the correct events.  Sorry about that :/

Cheers,
Julien
