Note that support for reading 4 block edids is only implemented since
commit cd004b3f4cd4169815c82bf9e424fda06978898a

drm: edid: add support for E-DDC
Which is merged into kernel 3.7. Have you tested with that?
Also please boot the linux machine with drm.debug=0xe added to your kernel
commandline and attach the complete dmesg output when trying to read a 4 block
edid.
