Hello,

I found on Jan Philipp Giel report
	http://fsai.fh-trier.de/~gielj/M6800N/
a new DSDT which solve the battery problem with the new BIOS 0205A. This new
DSDT was hacked by Ycarus, here the first lines from the .dsl version:
=====
/*
 * Intel ACPI Component Architecture
 * AML Disassembler version 20030918
 *
 * Disassembly of dsdt.dat, Tue Mar  2 23:05:23 2004
 *
 * Modified version of DSDT from Asus M6800N bios version 0205A
 * This version now report battery state under Linux.
 * Bug : Ac_adapter state is always off-line
 * Modified version by Ycarus (Yannick Chabanois)
 * chabanois(at)ifrance.com
 *
 */

I just tried it on 2.6.3 + ACPI 20040220 + ACPI DSDT in initrd 2.6.1 and now the
battery0 is read correctly:

IMHO someone should send this hacked DSDT to ASUS in order to have a new BIOS
version which doesn't need an hacked DSDT, am I right? Could this be useful?

Thx, bye,
