Hi,

i tried to flash libreboot (and coreboot) to my T400, using the latest sources 
from git.

Unfortunately the LCD stays black, even if the system SEEMS to boot in the 
background. (I already tried spkmodem for debugging but wasn't very successful)

After talking with fchmmr, i extracted the EDID
