I don't know why the Xorg log says "No input driver/identifier specified (ignoring)" when my /etc/X11/xorg.conf.d/10-synaptics.conf file states explicitly that the driver is "synaptics":
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection
Thanks for your consideration.
Everything works except for the two finger scrolling on my synaptics touchpad.
There is some info:
Kernel: 3.0.6-2 (stock)
Synaptics Touchpad driver: 1.5.0-1 (lastest)
Right side scrolling works fine, two or three finger tapping doesn't work either.

As for multitouch support:
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?id=4aa16879bd5084f061a55e5b8a0754e1b037212a
The emulation for devices that don't support it correctly has been reverted, as it was giving too much random events. I think you can enable it again by experimenting with the "EmulateTwoFingerMinZ" option, but the value for that depends on how sensitive your touchpad is.
