I couldn't see anything of note in the syslog, so attempted to bisect the
problem some - although building takes considerable time on this machine
(note 32bit).

4.3.0rc6 - bad
4.3.0rc7 - bad
4.3.0rc2 - good
4.3.0rc4 - bad (049e6dde7e57f0054fdc49102e7ef4830c698b46)
4.3.0rc3 - good (9ffecb10283508260936b96022d4ee43a7798b4c)

So problem (no LCD backlight) must have been introduced between those.
