[opensuse-kernel] Aliens ate /proc/acpi/battery/BAT*

5 May 2015

      I have a hunc "this is a feature, not a bug" ;-), but with
the update to kernel 4.0, /proc/acpi/battery/BAT* is gone.

Is there a way (config option we could enable) to get this
back?

If not, how can I best re-implement something like the little
script below (which works for more than one battery in case 
you are wondering about the complexity):

#!/bin/bash

sum() {
  s=0;
  while read l; do
    i=`echo $l | cut -d' ' -f1`
    printf "%5s " "$i"
    s=$(($s+$i))
  done
  printf " = %s\n" "$s"
}

for v in "design capacity" "last full capacity" "remaining capacity" "rate"; do
  printf "%18s = " "$v"
  cat /proc/acpi/battery/BAT*/* | grep "$v:" | cut -d: -f2 | sum
done
