With xorg intel driver, is it possible to bypass DDC and use a higher resolution?

Yeah, the 1920x1080 resolution is probably in some CEA EDID block, which
we aren't parsing yet (the EDID parsing code lives in the X server,
btw). I think there's a patch around that adds more EDID parsing stuff.

Until the X server gets this code, you can add the right mode line to
your xorg.conf file, I'm betting a 1920x1080 reduced blanking mode will
work just fine (using 'cvt -r 1920 1080'):

# 1920x1080 59.93 Hz (CVT 2.07M9-R) hsync: 66.59 kHz; pclk: 138.50 MHz
Modeline "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync

Yeah, it's a pain, and yeah, I hope to see this code added to the X
server soon.
