Alps touchpad wont scroll


I am trying to get everything working with Ubuntu 4.1 (based off Debian unstable) on my Sony v505-bx. This is the first time I have tried linux on a laptop, and I am still kind of new at linux.
The problem is that the scroll areas wont scroll. I have the synaptics driver. But what has me confused is that the driver seems to be working as tapping works, and horizontal scrolling does something.
Here is my current mouse setting in the xf86config-4 file:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/event1"
Option "Protocol" "auto-dev"
Option "LeftEdge" "120"
Option "RightEdge" "830"
Option "TopEdge" "120"
Option "BottomEdge" "650"
Option "FingerLow" "14"
Option "FingerHigh" "15"
Option "MaxTapTime" "180"
Option "MaxTapMove" "110"
Option "EmulateMidButtonTime" "75"
Option "VertScrollDelta" "20"
Option "HorizScrollDelta" "20"
Option "MinSpeed" "0.2"
Option "MaxSpeed" "0.5"
Option "AccelFactor" "0.01"
Option "EdgeMotionMinSpeed" "15"
Option "EdgeMotionMaxSpeed" "15"
Option "UpDownScrolling" "1"
Option "CircularScrolling" "1"
Option "CircScrollDelta" "0.1"
Option "CircScrollTrigger" "2"
Option "SHMConfig" "on"
EndSection

If I change the "Protocol" to "alps" the scrolling works, but the mouse movement, and tapping sensitivty is so high that the pointer just jumps all over the place.

In the trouble shooting guide on the synaptics driver page it says "If you are using a 2.6 linux kernel, check the /proc/bus/input/devices
file. The touchpad should be identified a "SynPS/2 Synaptics TouchPad"
or an "AlpsPS/2 ALPS TouchPad". If it is identified as a "PS/2 Generic
Mouse", something is wrong." but my touchpad is identified as PS/2 Generic Mouse. It then says that I should "Arrange so that the kernel initializes the USB subsystem before thePS/2 touchpad. Initializing the USB mouse sometimes di sables the BIOS emulation. Compiling psmouse as a module and loading it in /etc/rc.d/rc.local usually assures the USB is initialized first." which seems to be the problem, as dmesg show the ps/2 mouse being initialized before the usb, but I have no idea how to change this.

Thanks
