Re: DSDT bugs on Acer Aspire 3023 WLMi - SOLVED

[Michael Doube <m.doube-aUOafQfIvX+1Qrn1Bg8BZw@public.gmane.org>]

Thanks to Benjamin Larsson for the tip:

1) Leave the DSDT alone - it is buggy but battery monitoring can work anyway
2) Install a recent kernel, 2.6.13 and above apparently.  I am using 
Fedora's 2.6.13-1.1526_FC4.i686 kernel
3) use kernel option ec_burst=1

Now battery monitoring works, and dmesg gives:
----------
ACPI: AC Adapter [ADP1] (on-line)
ACPI: Battery Slot [BAT0] (battery present)
ACPI: Power Button (FF) [PWRF]
ACPI: Lid Switch [LID0]
ACPI: Sleep Button (CM) [SLPB]
------------

Sweet as.

Thanks to whoever was responsible for making this work, your effort is 
much appreciated.

Mike
