The actual solution to the problem is long. acpi_status should not be used outside of acpi-ca. However, it is. In many, many places. The real solution is to go around and re-write all the apis that export acpi_status to drivers, and then fix all the drivers which rely on acpi_status (and other acpi-caisms ). This fix, while ugly, solves the immediate problem in an expedient way. However, I'm certainly open to suggestions about nicer ways to do it.

Here's an alternate way to solve this problem - also easy, that may look nicer. (thanks arjan).
