The issue is most likely with GTK smooth scrolling. It likely doesn't honor the xmodmap button mappings, as that's sort of a hack that has worked because of the poor scrolling implementation in X. I don't know what the proper resolution is, but I'm pretty certain it's a bug that needs to be resolved in GTK somehow, or marked as "won't fix" by them.
