I have a SteelSeries Ikari laser mouse which is rated for 3200cpi and so is very sensitive. I have tried to set mouse sensitivity and acceleration in gnome mouse panel to zero without any affect, it still goes way too fast for any normal desktop usage.

How can I slow down my mouse?

(I know, I could just turn down the sensitivity in the mouse itself, but I was able turn down the sensitivity down in Windows, so I want to do the same in Linux.)
