Linux On My Samsung

I pulled in a kernel update for the Lucid UNR yesterday and my Samsung N150's backlight Fn keys have stopped working. I've tried several reboots to no avail. Everything else looks like it's still working well.

Any ideas? I miss being able to adjust my backlight

Worked perfectly, thanks a ton!
