The current hal configuration is wrong. The culprit is the hald-addon-macbookpro-backlight, which assumes the ATI graphics card, which MBP3,1 does not have. A similar problem exists for MBP4,1. The MBA1,1 is not even listed.
I have managed to make it work on my MBA by creating a new addon, hald-addon-applesmc, which simply uses the sysfs devices created by applesmc to control the backlight. The same procedure should work for both MBP3,1 and MBP4,1, so I will carry this patch upstream and hope for the best.
If you are interested, I can publish the fdi configuration change and a i386 and/or amd64 binary here for further testing.
