It looks to me like udev is the problem (I read udev is slowly being
integrated into DeviceKit).
Looking at /lib/udev/rules.d/66-xorg-synaptics.rules I see:
ACTION!="add|change", GOTO="xorg_synaptics_end"
KERNEL!="event*", GOTO="xorg_synaptics_end"
ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="xorg_synaptics_end"
# Placeholder for platform specific quirks needing
# ID_INPUT.tags to be set.
ATTR{[dmi/id]product_name}=="Inspiron 1011", ENV{ID_INPUT.tags}="inspiron_1011"
ATTR{[dmi/id]product_name}=="Inspiron 1012", ENV{ID_INPUT.tags}="inspiron_1012"
ATTR{[dmi/id]product_name}=="Inspiron 1120", ENV{ID_INPUT.tags}="inspiron_1120"
ATTR{[dmi/id]product_name}=="HP MiniNote 1000", ENV{ID_INPUT.tags}="mininote_100
LABEL="xorg_synaptics_end"
I don't know what the tagging is for but I tried adding:
ATTR{[dmi/id]product_name}=="VPCEB2S1E", ENV{ID_INPUT.tags}="VPCEB2S1E"
and after a reboot, no change.
But if udev reads DMI data to detect the hardware, by looking at the
output of dmidecode, I couldn't see any touchpad device on my system,
so maybe the DMI data is missing or dmidecode can't read it.
Hope this helps.
