Dmitri,
I fixed one line in the wpce775x_serio driver which looked like a typo - 
hope I got that right:

	for (i = 0; i < count; i++)
-		serio_interrupt(ps2if->serio, ps2if->data_in[1], 0);
+		serio_interrupt(ps2if->serio, ps2if->data_in[i], 0);
	}

I tried running with psmouse but it didn't work. The touchpad was never 
detected as a synaptics touchpad. I looked at the dataflow from the 
device and it wasn't responding to the commands that synaptics_detect() 
was sending it. It eventually showed up as an unknown logitech mouse. I 
can see data being passed through the serio driver but the logitech 
driver can't process it.
