Hi, For at least two reasons it would be beneficial for some code outisde the graphics driver(s) to know if the KMS are used. First, in the non-KMS (ie. UMS) case we probably wouldn't want to call acpi_video_resume(), because that has a potential to mess up with the GPU (it actually is known to do that on at least one system). Second, in the KMS case, we'd be able to skip the kernel VT switch, because the KMS driver uses its own framebuffer anyway. So, is there any reasonable way to check that from the outside of the graphics driver? It should be general enough to cover the cases when there are two graphics adapters with different drivers in the system and so forth.
