Default Mouse wheel issue on current Ubuntu and Debian releases

On Ubuntu Maverick 32-bit, Ubuntu Natty 64-bit and Debian Squeeze 64-bit
the mouse wheel doesn't work. It's ok for older Ubuntu and Debian
installs, but those aren't installed any more, just old openSUSE 11.2
64-bit still is on my computer and there the mouse wheel still and
always is ok.
Sometimes the mouse wheel randomly works for those Ubuntus and the
Debian install, but this happens very seldom.

It's not related to the usage of a xorg.conf, this happens with or
without a xorg.conf, at least I tested this for Debian.

For Ubuntu Natty and Debian stable I tried this (see
http://www.larsen-b.com/Article/341.html ).

# apt-get update
# apt-get install xserver-xorg-input-kbd xserver-xorg-input-mouse

And to /etc/X11/xorg.conf I added

Section "ServerFlags"
Option "AutoAddDevices" "False"
Option "AllowEmptyInput" "False"
EndSection

but this didn't change anything.

Then I removed the xorg.conf from Debian stable, to ensure that it's not
xorg.conf related, but the issue didn't disappear.

On Ubuntu Natty I edited ..................................

$ cat /etc/hal/fdi/policy/*.fdi
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->

<!--

.............................. and command out the server flags and any
mouse entry too from xorg.conf.

Rebooting Natty for the first time the mouse wheel did work.
Rebooting Natty for the second and any additional time the mouse wheel
didn't work anymore.

For the moment I let this issue rest and try to fix other debianoid
issues on my machine. Again, for older installs of Ubuntu and Debian
there never was such an issue for the mouse wheel. I don't know how it
is for the current Suse release. The Suse release on my machine is ok
for the mouse wheel, but as mentioned before, 11.2 is an outdated
release.
