DSDT bugs on Acer Aspire 3023 WLMi

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

Hi all

I've been trying to get the smart battery system going on my Acer Aspire 
3023 WLMi notebook under kernel 2.6.12.2.  As far as I'm aware the 3023 
is a variant of (but basically very similar to) all the 3020 and 5020 
notebooks.  It is quite different to the 3000 / 5000 series.

I've tried the sbs-cm patch (took a punt, didn't work), and I've tried 
the instructions at ACPI4Linux.

I've managed to remove some of the bugs from the dsdt.dsl using the 
error and warning messages from the iasl compiler, but still these 
warnings remain, and I don't know how to get smart battery monitoring 
going.  My most bug-free dsdt.dsl is posted at 
http://acpi.sourceforge.net/dsdt/view.php?id=451.

dmesg gives:
