Yes. Even tried to remove vc4.ko from the filesystem, suspecting that
blacklisting didn't work for some reason. Didn't help.
I suspect then something is getting powered off because it doesn't

For touch to actually work yes, driver from rpi tree @ github must be
ported over. IIRC it's connected via i2c.
Display output doesn't need the touch driver though.
Sure, but I wasn't sure exactly what you were after.
