To fix that completely we'd need to avoid calling acpi_video_resume() in the non-KMS case, but it's not clear how to tell the ACPI driver which case we're in. It's not certain how to reliably distinguish the KMS and non-KMS cases at this level in the first place. > Can we send this to stable for .32 and .33? That depends on Len.
