Yes, it seems to be the same problem, despite it appears on different kernel versions in Ubuntu:

Lcd brightness control works with:
-Jaunty's linux-image (the Fn keys don't work, but Gnome can control the brightness)
-Karmic's linux-image-2.6.30 (before changing to 2.6.31),
-http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30.5/ (the one I'm now using)

And it does NOT work with:
-Karmic's linux-image-2.6-31-5 to -10, as mentioned above
-http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.31/

So in Ubuntu there seems to be a regression in kernel 2.6.31.

Note: I also get the same message when removing and inserting sony_laptop module:
"sony-laptop: brightness ignored, must be controlled by ACPI video driver"
