I'm compiling a kernel just for learning purpose, and I almost get all things working, bluetooth, hdmi, usb, card reader, webcam, wifi... etc. But I can't make touchpad works, all that I know about it is...

So this is basically all that I know about it, lspci -k doesn't show the touchpad, and lsmod just list two modules related i2c_hid and hid_multitouch I've tested the others disabling them and seeing if it was related if touch. And this is the latest config file that I compiled and I don't know how to get support for this touch, I already enabled everything related with i2c, usb, hid that have elan, elantech, synaptics, designware and nothing worked.
