commit 66c5ee0ff4690e630a69656331fd9d545c99c26c

    config/APM: Add option to disable building of APM support on Linux
    
        APM support in the Xserver was used to restore the console mode
        prior to a power management event. This was to ensure the mode
        upon suspend/resume was one that the system firmware or kernel
        could deal with.
        APM support is now largely obsolete, KMS drivers don't require a
        mode restoration anyhow. Therefore it should be possible to disable
        this feature.
    
    (small modification by keithp - move test for XF86PM flag after check
    for APM, then move XF86PM flag to xorg-config.h.in)
