3.15-rc3 syslog with more logging

This one came up to the "VESA" resolution, but when I tried to manually force
the native resolution, it didn't work.

Force script is described up-bug, I think, but in case it's not, it's just:
$ cat fixup-display.sh 
xrandr --newmode '2560x1440_0.0' 241.50  2560 2608 2640 2720  1440 1443 1448
1481 +hsync -vsync
xrandr --addmode DP1 '2560x1440_0.0'

(Timings were extracted by connecting directly via displayport, in which case
the box comes up to native resolution w/o a problem.)
