I just remembered getting the backlight to work some time ago with nouveau on my powerbook. I looked around and found this message from Andy Wingo: http://lkml.org/lkml/2008/1/12/170 This is his code that I used at the time, available here: http://wingolog.org/pub/nvbacklight-0.1.tar.bz2 To get it to work on a recent kernel, I had to use this patch: diff --git a/nvbacklight.c b/nvbacklight.c index 927d36b..1af10e0 100644 --- a/nvbacklight.c +++ b/nvbacklight.c @@ -178,7 +178,7 @@ static struct fb_info *nvbacklight_attach(struct pci_dev *pd) par->fpSyncs = NV_RD32(par->PRAMDAC, 0x0848) & 0x30000033; bd = backlight_device_register("nvbacklight", &pd->dev, par, - &nvidia_bl_ops); + &nvidia_bl_ops, NULL); if (IS_ERR(bd)) { printk(KERN_WARNING "nvbacklight: registration failed\n"); goto bl_device_register_failed; You'll have to install linux-headers-powerpc, but then a simple make and insmod and it works nicely here.
