I think this is a bug in gnome-settings-daemon. Here's why:

The touchpad on Thinkpads (see /etc/acpi/events/lenovo-touchpad) is toggled by /etc/acpi/asus-touchpad.sh. On my R400, pressing Fn+F8 successfully changes the value of the Synaptics Off (269) xinput property. The Device Enabled (132) property, however, is set to 0, so the touchpad is disabled for some reason, but enabling it by xinput set-int-prop 11 "Device Enabled" 8 1 doesn't work when the gnome-settings-daemon is running. If I kill it, I can enable the device through xinput set-int-prop, and then the Fn+F8 shortcut works as expected.
