How do you disable mouse scroll wheel acceleration in Mac OS?

Using a fairly generic gaming mouse (no Mac drivers available) on Leopard, I've noticed that the faster I scroll, the more distance I travel per "tick". I find this quite annoying, yet there doesn't appear to be a way to control the mouse scroll acceleration.

On Windows and Linux, I'm used to having the mouse scroll three lines per tick.
Can something be done about this?

This question was marked as an exact duplicate of an existing question.

A very similar problem, mouse pointer acceleration, has been discussed at great length, with the apparent conclusion that there's no built in way, but there are some hacky ways to do it. See if any of the info there helps you. – nhinkle Aug 16 '11 at 7:30
@nhinkle: I did. No luck so far. – oKtosiTe Aug 16 '11 at 18:59
My sense is that there's probably no way to fix it. – nhinkle Aug 16 '11 at 19:01
oh totally, it's good that you asked, I'm just saying it's not likely to get solved, at least currently. – nhinkle Aug 16 '11 at 23:06

I believe that it would answer your question. There's a "thing" call "inertia" scrolling in Mac OS X, which enables you to scroll faster without having to scroll too much with the mouse. Please consider change the setting to "without inertia" and see if that's what you need.

P.S: Sorry I don't have Leopard machine available and my screenshot is for Mountain Lion. Please tell me if this doesn't work with Leopard. Sorry for any inconvenience.

I only have that inertia option for my trackpad. Doesn't it just disable inertial scrolling? (Where views keep scrolling after you flick a multi-touch surface.) – user495470 Nov 18 '12 at 7:06
Sorry but I'm not sure. For me, I have both 2 options "with inertia" and "without inertia". – Ngoc Pham Nov 18 '12 at 8:18
