I also have the same problem on a Toshiba T110/00D. It has the Intel Mobile 4 Series Chipset and graphics (more specifically Intel GMA 4500M).
The fix somewhat works, but I can't decrease/increase brightness of panel/cairo-dock, because they still remain bright. There's also the problem that when a pop-up window comes up, and when I open up a new window, that also remains at full screen brightness. But these are minor quibbles, as I can finally reduce the screen brightness :-D
I really do hope the Ubuntu devs get this fixed up too :-D
