[SOLVED] touchpad is not recognized

Hi, I could not find a relevant post so I hope anybody will have an idea:

my touchpad (on Dell D830) stopped responding after I experimented with the AUR package psmouse-elantech. Now it seems the device is not recognized at all. I actually have dual boot with Mint and everything works there so the hardware should be fine.

EDIT: With the recent update of kernel (to 3.7.3-1-ARCH) the problem disappeared. Marking solved but the cause is not clear for me since I tried to re-install kernel too.

output of xinput:

[david@archlinux Downloads]$ xinput
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ USB Optical Mouse                       	id=9	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Video Bus                               	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=8	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=10	[slave  keyboard (3)]
    ↳ Dell WMI hotkeys                        	id=11	[slave  keyboard (3)]

I should see something like this:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ USB Optical Mouse                       	id=9	[slave  pointer  (2)]
⎜   ↳ DualPoint Stick                         	id=11	[slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS DualPoint TouchPad        	id=12	[slave  pointer  (2)]
⎣ Virtual core keyboard    
    ....

I use evdev without xf86-input-synaptics installed. In the past this worked fine except of some missing touchpad features. Installing synaptics driver did not help.

/etc/X11/xorg.conf.d/10-evdev.conf :

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

I suspect this is something around dkms installed by the above package but my knowledge does not go that far. Any hints are appreciated.
