It definately sounds like you are not using the CVS sources, because the 945GM is supported. Look in your drm_pciids.txt file for this entry.... 0x8086 0x27A2 0 "Intel i945GM" Closing. As this isn't a bug. I didn't know the drm module would automatically load the card-specific sub-module. Can you try 'modprobe i915'?

I'm using current DRM CVS sources on a laptop with an integrated 945GM controller, running Debian Sarge on a 2.6.15.6 linux kernel. When i load the 'drm' module, i get the drm version output, but no card-specific information : # modprobe drm Linux agpgart interface v0.101 (c) Dave Jones [drm] Initialized drm 1.0.1 20051102 # lspci
