Hi!
I have a problem with my Synaptics Touchpad: I cannot use it's wheel
function, although the pms driver supports it.

The relevant (AFAIK, full dmesg is at the end of message) parts of dmesg:

pckbc0 at isa0 port 0x60-0x64
pckbd0 at pckbc0 (kbd slot)
pckbc0: using irq 1 for kbd slot
wskbd0 at pckbd0: console keyboard, using wsdisplay0
pms0 at pckbc0 (aux slot)
pms0: Synaptics touchpad version 6.3
pms0: Up/down buttons, Palm detect, Multi-finger
pckbc0: using irq 12 for aux slot
wsmouse0 at pms0 mux 0

In the kernel config I have:

options         PMS_SYNAPTICS_TOUCHPAD

XF86Config, InputDevice section:

Section "InputDevice"

# Identifier and driver

    Identifier  "Mouse1"
    Driver      "mouse"
    Option "Protocol"    "wsmouse"
    Option "Device"      "/dev/wsmouse"
    Option "Buttons"    "5"
    Option      "ZAxisMapping"  "4 5"

I tried to tweak sysctl settings of pms driver:

hw.synaptics.up_down_emulation={0|1|2} - none of the three values worked

I have no other ideas... If anyone can help or made a Synaptics
touchpad work under X, please respond!
