[ACPI-sppt] ACPI Error messages with 0619 and 0714

I have a Compaq Evo n610c laptop that was running 2.5.75-mm1 (061903 
ACPI) and now 2.6.0-test1-mm1 (071403) ACPI and have the following 
entries about AE_AML_BUFFER_LIMIT and AE_AML_UNINITIALIZED_LOCAL in the 
kernel logs:

I was originally running with Compaqs 11/2002 BIOS which I updated to 
the latest 05/2003 BIOS which did resolve some critical issues with 
ACPI.  With the older BIOS, thermal would not load at all due to these 
errors and the fans would never run.  With 0714 and the new BIOS, 
thermal seems to be operating properly and the fans are running so I'm 
not boiling over (phew!).  I load the ACPI modules from rc.local as follows:

# Load all ACPI modules if we can
if [ -d /proc/acpi ]; then
        for i in processor ac battery fan thermal button; do
                /sbin/modprobe $i
        done
fi

Loading battery causes:

ACPI-1121: *** Error: Method execution failed 
[\_SB_.C045.C059.C0E2.C13F] (Node c157fd20), AE_AML_UNINITIALIZED_LOCAL
ACPI-1121: *** Error: Method execution failed

ACPI-1121: *** Error: Method execution failed [\_SB_.C198._BTP] (Node 
c157bd00), AE_AML_UNINITIALIZED_LOCAL
ACPI: Battery Slot [C198] (battery present)
ACPI: Battery Slot [C199] (battery absent)


Though it does seem to work properly.  Is this just a dorked DSDT from 
Compaq (imagine that...) or something else?  Again, with the new BIOS 
(even Compaq urged that system be upgraded to this newer BIOS) and the 
latest patches, I seem to be operating correctly and stable but I would 
like to see these errors resolved wherever the problem happens to lie.
