It is not enough. If do not want to recompile full kernel, but just only
psmouse.ko I think that the easiest way is to change this define

 #define psmouse_dbg

in file drivers/input/mouse/psmouse.h to call dev_warn instead dev_dbg.
And then just compile psmouse.ko and reload it.

Thanks, that seemed to do the trick.  This is what I get from dmesg now:
