Something's different on my freerunner:

lsinput shows the "missing" devices:

Don't tell my touchscreen it doesn't exist :)

JFTR: I'm not running hal, which might change something ...

My /etc/X11/xorg.conf contains:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "tslib"
        Option      "Device" "/dev/input/event1"
        Option      "Width" "480"
        Option      "Height" "640"
EndSection

My xserver-* packages:

deanna:~# dpkg -l xserver-* | grep ^ii
ii  xserver-common             2:1.7.4-2                    common files used by various X servers
ii  xserver-xorg               1:7.5+2                      the X.Org X server
ii  xserver-xorg-core          2:1.7.4-2                    Xorg X server - core server
ii  xserver-xorg-input-evdev   1:2.3.2-3                    X.Org X server -- evdev input driver
ii  xserver-xorg-input-kbd     1:1.4.0-1                    X.Org X server -- keyboard input driver
ii  xserver-xorg-input-tslib   0.0.6-1+b1                   tslib touchscreen driver for X.Org/XFree86 s
ii  xserver-xorg-video-fbdev   1:0.4.1-1                    X.Org X server -- fbdev display driver
ii  xserver-xorg-video-glamo   0.0.0+20091108.git9918e082-1 X.Org X server -- SMedia Glamo display drive

Or is the "old" udev responsible? With the Debian kernel the newest
one can't be installed:

deanna:~# dpkg -l udev
ii  udev                  149-2                 /dev/ and hotplug management daemon

Cheers,
