This appears to have gotten rid of the flickering, but the side effect is that I'm now unable to adjust brightness at all. http://www.voria.org/forum/viewtopic.php?f=3&t=821&hilit=brightness+flicker

In short:

1. edit the "/etc/modprobe.d/blacklist.conf":
at the end add this line: blacklist samsung_laptop

2. edit "/etc/default/grub/" (if you are using grub 2):
search the line with GRUB_CMDLINE_LINUX_DEFAULT=. add the following to the string: acpi_backlight=vendor

3. execute update-grub

4. reboot your os
