rfraxford and marco-assini, you are the only two people on this bug who still have this problem...
could you attach here the following, please?
1) "lspci -vvnn > lspci.log" (attach the lspci.log file)
2) /etc/X11/xorg.conf
3) /var/log/Xorg.0.log
(marco-assini, ignore the previous request for dmesg.log)
Also, both of you, please try booting with an empty /etc/X11/xorg.conf file...
