Can you send an EDID dump? Use i2cdump:
http://libreboot.org/docs/misc/index.html#get_edid_panelname
I think I need some more help to provide the EDID dump.
sudo rmmod i2c-dev delivers nothing
and
sudo i2cdump -y 5 0x50

Do I have to change the value for -y as mentioned in
http://libreboot.org/docs/misc/index.html#get_edid_panelname ?
How to find out which is the value needed?
I also tried "sudo get-edid | strings" which results in:
This is read-edid version 3.0.1. Prepare for some fun.

Looks like no busses have an EDID. Sorry!

I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern

Hi,
the panel
IDtech N150U3-L01 (15.1" 1600x1200) listed as untested on
http://www.libreboot.org/docs/hcl/index.html#supported_t60_list
is working with libreboot on a T60 and inverter board P/N
42T0078 FRU 42T0079.
One Issue: It doesn't show the "libreboot bootscreen", but the
installed operating system starts and everythings works fine so
far.
Any idea what is causing the problem? I tested with the newest
rom from http://www.libreboot.org/git/rom/libreboot_t60.tar.xz.
best regards,
chp
I'm not sure what causes it, but you can use the serial out on the
"Advanced Mini Dock" to see GRUB via a text-based (serial)
console.
