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!

The EDID data should not be trusted as the VBE call failed

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