Okay, I tested the kernels in comment #21. With all three of them, I still have touchscreen functionality. I blacklisted i2c_hid at boot time. After modprobe'ing the i2c_hid module, the touchscreen still works, but scrolling with the touchpad does not work anymore (thus, it is the same behaviour as the standard kernel exhibits).
I am now testing the kernels in comment #24.
