Confirming that the 738 releases fixes the 'No valid modes found' error for me.
I had exactly the same problem, I was dropped to a text-only login screen after a successful boot. I have followed the guide at https://help.ubuntu.com/community/OpenChrome to build and install the 738 release. Rebooted the machine and immediately got a graphical login screen.

Thanks for the quick fix.
