There is some more misbehavior regarding ddcprobe: On an ASUS Pundit 
with onboard NVIDIA graphics we get no output at all: "edidfail", but 
with hwinfo we get all information - but we would like to use ddcprobe, 
because it is a lot faster.

see the Attachment for outputs of ddcprobe, lspci and hwinfo.

Should I provide more information about hardware or software? All these 
tests come from a pre-boot busybox environment, but on my laptop I have 
a complete linux system running when ddcprobe fails.
