Created attachment 60730 [details] dmesg with proposed patch and drm.debug=4

Your system doesn't use a NUTMEG chip. It uses TRAVIS for both VGA and LVDS. Please attach a copy of your vbios:

(as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom
