Dear Stefan, I've installed Karmic from new and the bringhtness problem persists. But now I can't find the menu.lst file to set the boot option. Before installing, I had tried to go back to the last patched kernel version with dkpg. I successfully changed the kernel, but the brightness control didn't come back. I'm attaching the dmesg output. My eyes will thank your efforts.
