I would like to confirm the bug, and provide additional data.

My definition of "slow": when I move my finger at 1 mm/s the cursor does
not move *at all*. Same when I roll the tip of my finger to drive the
cursor where I need it to be (that's what I usually do when I need
single-pixel precision).

I can watch the events generated by the kernel with synclient, but all of them are ignored by X up to a certain motion speed, beyond which the cursor starts moving, but in jerky sort of way.
 
For me, this started happening very recently (about 2 days ago), but I was mostly reading during that time and didn't notice a definite event that I could link to the change. If this is indeed caused by xserver-xorg-input-synaptics, I would like to know which was the last working version. I did a lot of precise work in Gimp just last weekend, and did not notice any inconvenience. In between, I have upgraded my nvidia-glx-180 to 185, and that is the only upgrade I am aware of, although I can't see how it would be related to the touchpad problem. Now I am unable to use  the touchpad for anything except selecting windows: I can't cut and paste and I can't even reliably put the cursor on the right line in a text editor. At the same time, external mice, pen tablet and the built-in track stick work smoothly.
