Only mouse cursor visible when using armsoc driver - [drm:fimd_win_mode_set] *ERROR* Invalid panel parameters

I updated my Samsung Chromebook to Ubuntu 14.04 and ran into an issue described on Ubuntu's bug tracker at https://launchpad.net/ubuntu/+source/xf86-video-armsoc
The system is perfectly usable using fbdev, but if I switch to using armsoc, I run into issues. Upon starting the X server, I see my mouse pointer on screen. About 4 seconds later, the lightdm login screen appears. About 3 seconds after that, the login screen disappears, and only the mouse pointer remains on screen.
dmesg is filled with '[drm:fimd_win_mode_set] ERROR Invalid panel parameters' messages
I am experiencing this issue with the version packaged with Ubuntu (0.6.0) as well as current git (ee9f1d96, 1.4.0).
