This issue is now fixed for me with recents kernels on Ubuntu 14.04. I'm
currently using 3.13.0-32-generic.
My amd fglrx driver is 2:13.350.1-0ubuntu2
My intel driver is i915-3.15-3.13-dkms
I have GRUB_CMDLINE_LINUX="video.use_native_backlight=1" into my
/etc/default/grub
Everything seems to work correctly (brithness, suspend/resume)
