[SOLVED - kinda] Xorg updates break mouse acceleration

I have a razer diamondback mouse, which until recently I'd been using xset m 1 0 to rein in.  Without this, the mouse has frighteningly high acceleration and is impossible to control.

After the updates it refuses to move unless I send it halfway across the pad first.  Running "xset m 1 1" suddenly makes the mouse impossible to control again.  There doesn't appear to be any middle ground.

Re: [SOLVED - kinda] Xorg updates break mouse acceleration

Well, it looks like there's a new, undocumented addition to xorg.conf, in the form of Option "Sensitivity" in your mouse section, a la:

Section "InputDevice"
    Identifier     "Configured Mouse"
    Driver          "mouse"
    Option       "Sensitivity" "0.5"
    Option         "CorePointer"
    Option         "Device" "/dev/input/mice"
    Option       "Protocol" "auto"
    Option         "ZAxisMapping" "4 5"
EndSection

Where Sensitivity can be anywhere from 0 to 1.0.  In addition, you must run

xset m 1 1

(disable acceleration and also have a threshold) to have the mouse work smoothly again.  As it is, a Sensitivity of around 0.4 or 0.5 roughly emulates what I had before.
