  Automatic hibernate on Dell Latitude E6410 because of phantom battery

Bug description:
  The Dell Latitude E6410 I've got here hibernates upon resume if no AC
  adapter is plugged in, with Oneiric. Apparently the kernel adds a
  second battery into sysfs only after resume that's not actually
  present but which is interpreted as being a battery with 0% charge.
  The power symbol in the panel is also telling me that a battery is
  missing.

  I guess the slot is the one of the DVD disk drive, where you could
  plug in a second one.  On boot I get this:

  [    2.352062] ACPI: Battery Slot [BAT1] (battery absent)

  If you read the /proc/acpi/battery/BAT1/* entries, the kernel drops
  the battery from sysfs again and the icon returns to the right battery
  BAT0.  Sadly the whole problem is critical as hibernation does not
  seem to work with Oneiric and this particular type of laptop. So
  there's certainly a kernel bug involved, but gpm also doesn't seem to
  handle the situation gracefully.

  The uname output is as follows: Linux roadrunner 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux
  The package versions in question are linux-image-3.0.0-12-generic 3.0.0-12.20, gnome-power-manager 3.2.0-0ubuntu1 and upower 0.9.13-1. (upower emits signals for both batteries in question and continues to poll the absent BAT1 every second.)

  There's a bug report over at RedHat which contains a workaround that touches those files post-resume. I did not test it yet and it's clearly a hack because the kernel shouldn't add it in the first place.
