This *IS* part of the ABI toward userspace, although I think Xorg uses the ioctl() interface.

yeah, but aspects of the ABI that applications do not rely on can generally be changed. OTOH, i've undone this aspect of the patch - /proc/mtrr is a legacy interface and changes to it are unnecessary. I kept the boot printout cleanups.
