Integrated new PS2 Voodoo code from rehabman - updated cypress driver in order to get it working again with new PS2 classes - disabled partially loading/communication from prefpane and mouse pref menu - added hardcoded feature activation Also, simplified use of the trackpad, since lot of people do not care of it: - removed 3 finger drag drop - added same behaviour of 3 and 4 fingers: usage.

Touchpad:

disable touchpad if USB mouse is plugged in and 'Ignore built-in trackpad when mouse or wireless trackpad is present' in Accessibility settings in System Preferences. (DONE)
calibrate movement/sensitivity to mouse (since they share the same config, it would be great not to have to adjust) (note: they are pretty close, but could be tweaked a bit) (DONE)
investigate using extended-W mode (haven't done much here except read the spec)
more gestures, as time permits (currently two-finger scrolling and three-finger swipe)
implement touch pad on/off in upper left corner (DONE)
clean up IOLog and allow for more information in Debug version (DONE)
if possible, implement LED indication for touchpad on/off (HP ProBook specific) (DONE)
implement high resolution mode for Synaptics (may already be implemented but not enabled in Info.plist) (DONE -- this version seems smoother than the one we were using)
implement palm rejection (accidental input) (DONE)
investigate doing something to make movement smoother (implement some kind of decaying average to smooth spikes in the input stream) (DONE)
implement a threshold of movement that will cancel a click drag (this would avoid unwanted drag detection) (one way to avoid this is for the user to set the fastest double click speed) (DONE)
Fix bug where trying to open a Menu with a tap does not work: Menu opens, but most of the time immediately closes. (DONE)

Keyboard:

Correct volume indications (for some reason these are not working right now) (DONE)
Make wireless key work for turning wireless on/off (HP ProBook specific) (DONE)
Allow for some limited form of custom key mappings (instead of hardcoding scan codes for specific laptops) (DONE)
Allow Fn+Fkeys to be swapped for FKeys (without Fn) (DONE -- use generic keyboard remapping above)

Mouse:

Implement LED on/off for Synaptics touch pads operating as a PS2 mouse (DONE)
Make the VoodooPS2Mouse.kext work for trackpads in mouse simulation mode. For some reason it arrived broken when I got the code. (DONE).
Add 'ignore input after typing' features to mouse driver. A little weird to make for a real PS2 mouse, but super nice for laptops with trackpads operating in mouse simulation mode. (DONE)

PrefPane:

Maybe test it and see if it works (it works, but there is a lot of options that don't make sense for Probook users)
Also, it would be nice if preferences would stick across reboots... (this works via synapticsconfigload, but needs work)

Great thanks to Dense for helping with activating vanilla trackpad prefpane
