The DSM failures,
 klog: HIGH Kernel message: [ 9.454424] ACPI Warning: \_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Integer], ACPI requires [Package] (20131115/nsarguments-95)

Seems to the mismatch Argument#4 that the graphic driver invokes the ACPI _DSM method,
From the ACPI spec, the arg3 type should be Package, but graphic driver calling _DSM method with Integer and Buffer,
So kernel complain about the mismatch the type of arg3. This is not the Bios issue, it should be the bug from the graphic driver doesn't follow the spec.

The failures,
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.PEG0.PEGP.DD02._BCL'.
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.PEG0.PEGP.DD02._BCM'.
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.PEG0.PEGP.DD02._BQC'.

 klog: HIGH Kernel message: [ 10.541990] ACPI Error: [\_SB_.PCI0.GFX0.DD02._BCL] Namespace lookup failure, AE_NOT_FOUND (20131115/psargs-359)
 klog: HIGH Kernel message: [ 10.541998] ACPI Error: Method parse/execution failed [\_SB_.PCI0.PEG0.PEGP.DD02._BCL] (Node ffff880070754a28), AE_NOT_FOUND (20131115/psparse-536)

these failures are from buggy firmware that implements _BCL, _BCM and _BQC on '\_SB_.PCI0.PEG0.PEGP.DD02 that uses the _BCL, _BCM and _BQC on \_SB.PCI0.GFX0.DD02, but the _BCL, _BCM and _BQC are not implemented.

these ACPI methods, might affect the brightness control, but brightness seems controlled by the_BCL, _BCM from \_SB_.PCI0.PEG0.PEGP.DD01. Need to confirm if there are no brightness issue on this machine.

For those syntaxcheck failure shouldn't need to be cared, these failures are due to the way the tables are being assembled without externals being reference. We are re-working the interfaces with the ACPICA assemmbler, iASL.
