Detecting a synaptics touchpad

Question

I'm attempting to use the synaptics drivers with X on my Dell 1420n, but the touchpad seems to be getting detected as a ps/2 mouse instead.
From /proc/bus/input/devices:
I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
After some googling, I found a mention of this problem at http://web.telia.com/~u89404340/touchpa … ooting.txt
It suggests that initializing the usb system before the mouse might fix this problem (It's currently doing the mouse first), but I can't figure out how to control the order with arch.
I'm also seeing this in dmesg:
input: Macintosh mouse button emulation as /devices/virtual/input/input0
which seems odd because it's not a Mac...
Any suggestions?

Answer 1

The kernel driver for regular PS/2 mice also takes care of the synaptics touchpad.  That's why they are seen as PS/2 mice.  Perfectly normal.
edit:
Ummm nevermind what I wrote before.  My touchpad is detected as  a SYNPS/2 mouse:
I: Bus=0011 Vendor=0002 Product=0007 Version=23b3
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input0
U: Uniq=
H: Handlers=mouse0 event0
B: EV=b
B: KEY=6420 70000 0 0 0 0
B: ABS=11000003
I'm positive the same module takes care of both PS/2 and synaptics mice, but I don't know why they get different names.
