Hello Alex.

Does not appear to be the case:
grep -R DRM_FBDEV_EMULATION ./*/.config  
./git_clone/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-4.14.83-gentoo/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.1.14-gentoo/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.2.10/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.3.6.custom/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.3-rc6/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.3-rc8/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-5.4-rc1/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux/.config:CONFIG_DRM_FBDEV_EMULATION=y
./linux-next-next-20190920/.config:CONFIG_DRM_FBDEV_EMULATION=y



Any other ideas? Would be appreciated!
Regards
Dmitri
