It has turned out that acpi key events seem to be handled correctly
and even the state of /sys/class/backlight/acer-wmi/brightness is
updated accordingly. The only problem is that this maintained
brightness state isn't applied to the actual backlight. It remains
at highest level. Google pointed me to this workaround for another
Acer notebook:
https://help.ubuntu.com/community/AspireTimeline/Fixes#Alternative%20fix%20for%2010.10
This uses the acpid to write the brightness value to the display
using setpci. And this works on my notebook as well (Acer Travelmate
5735Z-452G32Mnss). Not pretty but better than nothing. Is Acer
not able to build proper notebooks? Or is it a kernel bug?
