You'll find attached
1) the log from running `cbmem -c` but I excluded the
last few lines that contain my GRUB menu; and
2) the results from /sys/class/drm/card0-LVDS-1/edid

I'm not using the latest libreboot beta but a very recent one
from May this year (one that includes the increased VRAM size and the
explicit c4 state).
