Yes that's the main problem. Lots of code i unused. Basically everything except BootVideoCardBIOS, that is use in ATI video driver. I've got two solution of this problem. First, mark all unused code by some macro and compile it only conditionally or remove it. But I not sure if someone use this death code for debug purposes.
Did you check if you really find any such code in your linked image? As I already explained, normally -ffunction-sections / -fdata-sections with --gc-sections should make sure any unused functions get dropped automatically.
