I've finally succeeded with adjusting the screen brightness.

Firstly, I've added acpi_fake_ecdt=1 option to boot parameters.
Then switched to the console and was able to adjust the brightness by

cat $VALUE > /proc/acpi/video/NVID/LCD/brightness.

However, this still doesn't work for adjusting the brightness from
within X.

The video module still would crash, too.
