[coreboot] ACPI Errors on Lenovo X201i

I see the following occurrence of HBDC in the ssdt.dsl (decompiled from
/sys/firmware/acpi/tables/SSDT, is that the right file?) just below the
scope of the main DefinitionBlock:
Name (HBDC, 0x00)
Additionally, I have got this warning: "iASL Warning: There were 2
external control methods found during disassembly, but only 0 were
resolved (2 unresolved)." Not sure if that is relevant for this issue.
