I now know exactly why this issue exists.
Happens only when there are too few brightness levels available, for example,
if your screen has 8 brightness levels
(/sys/class/backlight/whatever/max_brightness = 7) as mine did, your brightness
up key will not work.

For Samsung netbook (NF310) users with samsung-backlight:
Add "options samsung_backlight use_sabi=0 force=1 levels=100" to
/etc/modprobe.d/modprobe.conf (create file if necessary)
