When you say "eGalax touchpad", you really mean touchscreen, right?
If your hardware is being detected as a touchpad then thats your
problem right there.  Touchpad == relative mouse-like device handled
by xf86-input-synaptics.  Touchscreen == absolute mode touchscreen
like device handled by xf86-input-evdev.

Based on your description of hardware, you should see two /dev/inputs.
 One for the wacom and one for the eGalax.  Are you seeing one
specifically for eGalax in your dmesg output?  We need to make sure
your really getting a kernel driver loaded for the eGalax part.

I find the "evtest" program extremely useful in verifying the kernel
side is working and which /dev/input goes to which hardware.  You can
google it for more info.

What kernel driver is being used by this hardware?  I hope its not a
binary blob because then your pretty much on your own getting it
working.

There is a unified X driver for generic touchscreen/mice/etc.  Its
called xf86-input-evdev.   It all depends on the kernel driver used to
which X driver gets loaded.  We'd need that info to go any further.

Good luck.
