Well, if this works, then maybe the Kconfig help text should be updated:

config ACPI_PROCFS_POWER
        bool "Deprecated power /proc/acpi directories"
        depends on PROC_FS
        help
          For backwards compatibility, this option allows
          deprecated power /proc/acpi/ directories to exist, even when
          they have been replaced by functions in /sys.
          The deprecated directories (and their replacements) include:
          /proc/acpi/battery/* (/sys/class/power_supply/*)
          /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
          This option has no effect on /proc/acpi/ directories
          and functions, which do not yet exist in /sys
          This option, together with the proc directories, will be
          deleted in 2.6.39.


Time to call the bluff now :)
