No sorry, doesn't look like its there(shows an an nvidia product), but I'm guessing its an alps on PS2 that's also capable with elantech, or the otherway around. In addition iv also taking apart the laptop and looked at the touch pad PCB, though no info on its maker.
Though windows just says its a generic PS2 mouse in a PS2 port that is precision touch pad capable.
Iv been looking into just replacing it with a synaptics pad, but i would have to put it though a usb part because the touchpad has a weird pin amount.
