Public bug reported:

Binary package hint: xserver-xorg-input-evdev

In Maverick the mouse acceleration optione in xorg.conf.d are ignored, resulting in insanely high mouse sensitivity with high dpi/cpi mouse.
This is solved by installing a newer version of xserver-xorg-input-evdev, in my case 2.5.0+git20100822.990540fa-0ubuntu0sarvatt from the xorg-edgers ppa.

This is also described in http://www.gossamer-
threads.com/lists/gentoo/desktop/211357#211357, where updating to 2.4
also fixed the problem on gentoo.
