Gentoo x64 Intel HD 4000 error

[cxz]

I am looking for help setting up Intel's video intel hd 4000: At the start of the kernel reports the error:
[drm] Initialized drm 1.1.0 20060810
[5.008137] [drm: drm_pci_agp_init] * ERROR * Cannot initialize the agpgart module.
[5.008173] DRM: Fill_in_dev failed.
like everything that is included in the wiki asked: CONFIG_AGP = y CONFIG_AGP_INTEL = y CONFIG_DRM_KMS_HELPER = y CONFIG_DRM_I915_KMS = y
Here my kernel config: http://pastebin.com/2qDJNg5z

Your dmesg is incomplete. But it seems that there is a problem with efifb handover. Disabe CONFIG_FB_VESA and CONFIG_FB_EFI in your kernel config.
