I wouldn't call the secret preferences macs have easily disabled. The vast majority of users encountering this problem won't be able to take advantage of this!

True it's not the easiest to do manually but there are plenty of preference panes that can open up this feature if you are motivated enough to fix it.

The problem is that I don't want to disable the acceleration entirely, I just want a _different_ acceleration curve: http://db.tidbits.com/article/8893

I'm not sure if this command will help with that.

But in any case, I'm sold on the trackpad now, and I'm not going back. :)
