I probably had tweaked my acpi script according to the information given at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which suggests to use setpci. And probably, the modified scripts /etc/acpi/asus-brn-down.sh (and -up) were deleted during the upgrade to raring.

Apparently, it has never worked off-the-shelf and it also affects UL30VT: http://askubuntu.com/questions/327736/unable-to-adjust-backlight-on-asus-ul30vt-neither-with-fn-keys-nor-with-xbacklig.
