Dave is right. We've had a moratorium on new files under /proc/acpi for some time now. The reason is that user-space should not know or care that something is supplied by ACPI -- for on other systems it may be supplied by something else.
So new stuff should have generic names under sys -- even if on a large body of systems the functionality beneath happens to be supplied via ACPI.
an example of old is the brightness stuff under /proc/acpi and in various platform specific drivers that scribble under /proc/acpi. The corresponding example of new is the backlight I/F under /sys.
