Indeed, 2.4.23-pre5 and 2.6.0-test5-mm3 include ACPI version 20030916,
which fixes the "Embedded Controller problem", as reported in
http://bugme.osdl.org/show_bug.cgi?id=1038

 and fixed in the first patch.

However, the "battery status" patch did not make it to the official ACPI
release, and you need to apply it later if you experience the "symptoms"
(lots of debug messages, dmesg showin only ACPI entries, etc, usually
after reading battery status from /proc/acpi/BAT...)

2.6.0-test5-mm4 includes this second patch. I'm using 2.6.0-test5-mm4 and
ACPI works quite well, but I'm unable to suspend to mem/disk and if I boot
when docked, there are some bugs and ACPI is disabled...
