Xorg update on Lenny killed evdev ?

["thveillon.debian" <thveillon.debian@googlemail.com>]

Hi all, I've just applied a few updates on my Lenny, including 
xorg-1:7.3+10, and after restarting the x-server my mouse was frozen 
(completely frozen from the login screen, but the rest of the system 
works fine including the keyboard).

After some testing I found out that using "evdev" as my driver wasn't a 
clever idea anymore, I now have to use "mouse" exclusively. My mouse is 
Logitech LX3 (that's cable usb), and my xorg.conf was :

Section "InputDevice"
  Identifier     "Configured Mouse"
  Driver         "evdev"
  Option         "CorePointer"
  Option         "Name" "Logitech USB-PS/2 Optical Mouse" ## that's 
from cat /proc/bus/input/devices
  Option         "HWHEELRelativeAxisButtons" "7 6" ## horizontal 
scrolling trick
EndSection

and the wheel was working both directions.

Now I have :

Section "InputDevice"
  Identifier     "Mouse0" ##xorg identifier changed with last update
  Driver          "mouse"
  Option         "Protocol" "auto"
  Option         "Device" "/dev/psaux"
  Option         "Emulate3Buttons" "no"
  Option         "ZAxisMapping" "4 5"
EndSection

and no horizontal scrolling of course ("HWHEELRelativeAxisButtons" 
doesn't work with driver "mouse").

Could the assassination of udev by xorg's update be considered a bug (or 
at least a treason) ?

Is there any way to get my bi-directional wheel to work again with the 
"mouse" driver ?

Thanks for any tip,

Thomas
