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:

.
> 	(**) 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.
