I don't know why I keep forgetting to include essential information. Sorry.

synaptics-0.14.6_2  The Synaptics touchpad X driver

Suppose I use the attached xorg.conf file, at some point,
/var/log/Xorg.0.log shows the following error:

(II) Synaptics touchpad driver version 0.14.6 (1406)
Synaptics_Touchpad no synaptics event device found (checked 10 nodes)
Synaptics_Touchpad The /dev/input/event* device nodes seem to be missing
(EE) xf86OpenSerial: No Device specified.
Synaptics driver unable to open device
(EE) PreInit failed for input device "Synaptics_Touchpad"
(II) UnloadModule: "synaptics"

As you said, it looks like synaptics is trying to use the "auto" protocol,
although the configuration file tells it to use "psm".

Now, if I put the attached patch in x11-drivers/synaptics/files, using the
same xorg.conf, synaptics will fail like this:

(II) Synaptics touchpad driver version 0.14.6 (1406)
(EE) xf86OpenSerial: No Device specified.
Synaptics driver unable to open device
(EE) PreInit failed for input device "Synaptics_Touchpad"
(II) UnloadModule: "synaptics"

It almost looks as if I have to hardcode the device too, because synaptics
certainly ignores my options.

Any ideas?
