 If instead of using the DVI connection, I connect to the same monitor but
 via VGA, the correct resolution is found:
 
 intelfb0: framebuffer at 0xffff800024b83000, size 1680x1050, depth 32, stride 6720
 
 X still uses the low resolution. Worry about DVI vs VGA first, and X later?
 
 Diff of kernel output  - DVI above + VGA now:
