This (6.1) box has a Logitech TrackMan Marble+ trackball.  When
pressed, the wheel acts like a center button.  When rolled, it
acts like a scrollwheel.  I have turned off Xterm scrollbars,
because the wheel does the job without taking up screen space.

I had a bit of a hassle when initially setting up Xorg, because
I didn't particularly want to enable console mouse and therefore
needed to have Xorg use the mouse directly.  Other than that, it
"just works".

There is no /etc/X11/xorg.conf on this box.  What I take to be
the relevant parts of /usr/X11R6/lib/X11/xorg.conf are:

Section "ServerLayout"
	Identifier     "X.org Configured"
	Screen      0  "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/psm0"
	Option	    "ZAxisMapping" "4 5 6 7"
EndSection
