This is the bug I'm most familiar with :)

kudzu now supports synaptics via evdev:

python
>>> import kudzu
>>> kudzu.probe(kudzu.CLASS_MOUSE,kudzu.BUS_UNSPEC,kudzu.PROBE_ALL)

Well if you are really keen you can install binary synaptics rpm from
http://pauln.truemesh.com/rpms/synaptics/

Ensure evdev is loaded on boot (I use /etc/rc.modules for this)

Change XFree86 config:

I have
                                                                                
Section "ServerLayout"
        Identifier     "Default Layout"
        Screen      0  "Screen0" 0 0
        InputDevice    "MouseS" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "DevInputMice" "AlwaysCore"
EndSection

...
                                                                                
Section "InputDevice"
        Identifier "MouseS"
        Driver      "synaptics"
        Option      "Protocol" "auto-dev"
        Option      "Device" "/dev/input/mice"
        Option      "Emulate3Buttons" "no"
EndSection

See README for more synaptic specific Options, the XFree86 rpms are provided to verify SDK patches working so can build from src.rpm.  If you want to test build you can install the XFree86-sdk provided.  Obviously if this gets in then the manual steps will be automagic.

Tap, horizontal and vertical scroll and friends should all work.

As far as the gpm patches go I did look at them and they include extensive refactoring from upstream.  I would imagine this is a case of if anyone cares about it they need to try and push upstream.
