Pre-KMS DRM (like i915drm) and DRM/KMS (like i915drmkms) are definitely not expected to coexist in the same kernel. > The i915drm line is present in both GENERIC and ALL, but it's commented > in both (yes, even in ALL).

The legacy pre-KMS DRM code base was kept around mainly for some ancient radeon device (like r100 or something) that broke in the DRM/KMS driver, and maybe for Intel i8xx, I don't remember. What's your motivation for using the i915drm driver?
