Thanks... On N900 it works for me in v4.16, but display stays blank in
v4.17-rc1...

And I'm starting to suspect I have somehow special N900, or maybe
special gcc version... Whether display on N900 works or not seems to
depend on completely unrelated config options :-(. Maybe it is timing
during boot or something.

Best regards,
