That's a really bad idea! This size checks are identented to assure, that important data which accidently follows the buffer can't be overridden by brain dead bios coders. Now you allow buffer overflow injection into linux from the bios! These are serious bios faults, in my DSDT I had to extend a buffer by 128 bytes to avoid a buffer overflow! The situation doesn't get better if we ignore such errors. We have to urge the manufacturers to correct the DSDT's. And the best way to do this is to recognise the faults and blame them. Herbert.

When turned on, the ACPI code will become forgiving of minor errors in the AML code. For this first cut, the patch and option will ignore region size errors. An off-by-one error is often found in the AML shipped with Toshiba laptops, even new models. This minor error prevents the AC module from operating without this patch. I urge the adoption of this patch (or something similar) into the ACPI code. This will make it much easier to install and proliferate Linux on a large category of laptops.
