Hello again,

I eventually have the i915/Intel HD4000 work along the 3.8 kernel: one must pass "i915.invert_brightness=1" kernel parameter

As for the Cypress Trackpad, it got even worse: it is now recognised a "ImPS/2 Generic Wheel Mouse", which is a regression compared to Quantal 3.5 Kernel:

# xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Atmel Atmel maXTouch Digitizer id=9 [slave pointer (2)]
⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
