Speaking of evdev, synaptics etc. I wonder whether anyone has an idea
how to set up the input devices for Xorg in a really useful way. 

The touchpad is easy:
Section "InputDevice"
        Identifier      "Touchpad"
        Driver          "synaptics"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/event1"
        Option          "Protocol"              "event"
        Option          "SHMConfig"             "true"
EndSection

But the trackpoint in combination with an external USB mouse gives me
troubles. ATM I'm using:

Section "InputDevice"
        Identifier      "Trackpoint"
        Driver          "mouse"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mouse1"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "true"
        Option          "ZAxisMapping"          "4 5"
        Option          "EmulateWheel"          "true"
        Option          "EmulateWheelButton"    "2"
        Option          "XAxisMapping"          "6 7"
        Option          "YAxisMapping"          "4 5" 
EndSection

Section "InputDevice"
        Identifier      "External USB Mouse"
        Driver          "mouse"
        Option          "Device"                "/dev/input/mouse2"
        Option          "SendCoreEvents"        "true"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "false"
        Option          "ZAxisMapping"          "4 5"
        Option          "EmulateWheel"          "false"
EndSection

That works, as long as the USB mouse is connected when the X-server
starts. If not I get the line

(EE) External USB Mouse: cannot open input device

which is not really suprising. Unfortunately hotplugging the USB mouse
doesn't work with this setup either.

OTOH, using the unified mouse device /dev/input/mice the hotplugging
works just fine, but then both devices get the same configuration. I
also played around with the "Dev Phys" and "Protocol" "evdev" options
for the mouse driver, but I can't get both "distinct configuration" and
"hotplugging" working at the same time. 

Any ideas?
