I think VoodooPS2Controller is only used for keyboard (trackpad/mouse does not work at all with it), as it is I2C Trackpad, so would be VoodooI2C, as per this
but latest version 2.6.5 does not help either
HID\DELL0816&COL03
Manufacturer: ALPSALPINE
on Intel(R) Serial IO I2C Host Controller - 9D60
edit
It is unlikely that they will ever work:Trackpad Keys and/or TrackPoint
