I've been having the same problem since updating to Xorg 6.9.0 two 
months ago. Before that, this problem did not exist for me. Here are a 
couple examples of what I see with use:

1) I'm going through my inbox in Thunderbird and I start scrolling up 
using the wheel to see messages. In addition to going up the list, it's 
also selecting all the emails that my mouse pointer happens to touch 
when I move the wheel up. This isn't good because then it marks lots of 
messages as "read" when I really did not read them.

2) I'm in Firefox viewing a website. I take my mouse pointer and hover 
over a link or a bookmark on my bookmarks bar. I keep the mouse over it 
and roll the wheel up once. It selects that link or button and goes to 
it as if I had left clicked on it.

Unfortunately I have not found a solution, but this is my configuration 
that was working for months up until upgrading to Xorg 6.9.0 (and is 
what I still have now):

----------------
Section "InputDevice"
         Identifier  "Mouse0"
         Driver      "mouse"
         Option      "Protocol" "auto"
         Option      "Device" "/dev/sysmouse"
         Option "Buttons" "5"
         Option "ZAxisMapping" "4 5"
EndSection
----------------

No flags for moused are in rc.conf. My mouse is a Microsoft Intellimouse 
Optical. Like yours, it is also hooked up through a USB to PS/2 adapter.
