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.

Well this looks like it might have something to do with it.... will
attempt a build just before it.

I can confirm that this is 'bad' (no backlight).
Although confusing this built labelled as rc2, despite being dated after
rc3 tag... double checking what I built.

Awesome sauce!
4281f46ef839050d2ef60348f661eb463c21cc2e + 2 patches works (backlight is
lit).
BTW my GFX is:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RV530/M56 GL [Mobility FireGL V5200]
Patches apply cleanly to Master too, will build overnight and test first
thing tomorrow,
Simon

Confirmed the patches work with master/rc7, backlight is working!
So the big question is whether we can get these included in 4.3 final...?
