The touchpad on the mini10v bothered me as well. There is no way to configure it.
I restored the OS X 10.5.7 image, which was installed with a genuine DuoCore Mac mini, to the mini10v. I found that the trackpad configuration is available from the system preferences. Now, I can change the tracking speed, trackpad gestures such as clicking, dragging.... The feature was missing when I installed the OSX 10.5.7 to the mini10v directly with two flash drives method.
