A diff is now available at
http://www.poupinou.org/Acer_Aspire_1644WLMi.asl.diff

It correct those errors:
- The two missing 'Z00A' are replaced by 'Ones' (note that you won't
need it when ACPICA will be upgraded to the latest version, this won't
happens in -stable in the short term, though).
- Eliminate all the ResourceSourceIndex when there is no ResourceSource
onto a Ressource descriptor.  This one actually is not a real issue,
but it's more clean now.


Ok now do that:
1- patch your Acer_Aspire_1644WLMi.asl,
2- invoke
iasl Acer_Aspire_1644WLMi.asl
That will create a DSDT.aml file.
3- copy this DSDT.aml to /boot
4- add those lines to your /boot/loader.conf:

acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/DSDT.aml"

reboot, and now you should be able to see the battery via
sysctl hw.acpi

Also look at 11.16.5.3 "Overriding the Default AML" in the handbook
for more details about this procedure:
