--- Comment #7 from erhard_f at mailbox.org ---
I built a new kernel and added following config options: CONFIG_VGA_ARB=y,
CONFIG_FB_RADEON=m, CONFIG_DEVTMPFS_MOUNT=y. I removed: CONFIG_FB_OF,
CONFIG_FB_SIMPLE. Still activated is; CONFIG_DRM_KMS_HELPER=m,
CONFIG_DRM_KMS_FB_HELPER=y, CONFIG_DRM_FBDEV_EMULATION=y.

"radeon"-driver still does not work, but at least the Xorg.0.log (see attatched
xorg.log_v2) and dmesg are more verbose. It seems to look for /dev/dri/ devices
but there are none. I only got /dev/fb0.
