    Hey Valery, a few things on this:

    This only works for mice that support the intellimouse protocol.

    Simplest way to find out if your mouse supports this is to kill
    the moused daemon, then issue the command:

    moused -p /dev/psm0 -t auto -d -f

    and read the first line, it will print out the model of the mouse
    (for example MouseMan+) then move the
    wheel up and down should generate a stream of events on the console

    If moving the wheel generates nothing, buy a different mouse.

    usb and serial mice with wheels can be tested with the same procedure
    except change the port -p of course.

    You should NEVER set the protocol for the mouse in either Xfree86 or
    xorg to anything other than sysmouse, when using FreeBSD. And, if
    your going to run X you should -always- run moused.

    Per the man page if you use moused, ps/2 or auto are the only acceptable
    protocols that are allowed to be set for the ps/2 port.

    During the FreeBSD installation for 4.X you are asked to set these up.

    moused -p /dev/psm0 -t auto

    is setup by the FreeBSD installation program and it will work just as
    well.

    Note - many wheel mice use a push on the wheel as a second button.

    This probably should be:

               Option "ZAxisMapping" "4 5"

    In fact, the only thing that generally needs to be added to this section
    is:

               Option "Buttons" "5"
               Option "ZAxisMapping" "4 5"

    For testing with twm:

    fill an xterm with text, scroll up and down.

    firefox also supports the scroll wheel.

    I don't understand how your X server got:

    > My X.log whith the 'sysmouse' protocol :
    .
    .
    > (**) Option "ZAxisMapping" "4 5"
    > (**) Mouse0: ZAxisMapping: buttons 4 and 5

    when you had configured

               Option "ZAxisMapping" "X"

    If I knew I could probably tell you why rebooting worked.
