It's bug #10265.

Matthias,
Does battery 2 keep on popping up and disappearing all the time after S3?
Or things became normal after a few seconds?

This is a piece of BIOS code from your acpidump.
_L13() {
   ...
   If (\_SB.BT1S)
   {
           Store (0x00, \_SB.BT1S)
           Notify (\_SB.BAT1, 0x01)
   }
   Else
   {
           Notify (\_SB.BAT1, 0x00)
           Store (0x01, \_SB.BT1S)
   }
   ...
}
I don't not why the BIOS sets/clears the BAT1 present flag (BT1S) every time
GPE 0x13 is fired.
But this can well explain the symptom on your laptop.
Linux/ACPI battery driver receives several ACPI Battery notifications when
resuming, checks the _STA method and finds that BAT1 is absent and then become
present.

I don't think this is a regression.
Matthias,
You said that 2.6.24 with one extra patch doesn't have this problem, can you
make a double check?
