<pre>An observation is that the nouveau code in nva3_get/set_intensity takes the
existing divider into account. However we only use that for nva3/5/8/f, not
nvaa/nvac.
Could you try changing nouveau_backlight.c:nv50_backlight_init to use
nva3_bl_ops for your chipset and seeing whether that fixes everything?
(Let me know if you're not sure how to do that, and I can put a patch
together.)</pre>
