Hi!
I am not 100% sure that that GPU is supported by the kms driver yet...
Do you have any way to hook up a serial console to the machine to maybe
be able to grab some output.  From a first look at things it certainly
looks like something goes wrong when setting up the graphics stack.  As
others have pointed out, once the KMS kernel module is loaded, the
console is unusable, so that's why the screen remains black once X has
exited (for any reason).
Is it also possible to get a dmesg as well as a complete X log (usually
from /var/log/Xorg.0.log).
Regards!
