You need to enable Framebuffer support in L4Linux and also the
Framebuffer-driver in the L4Linux (L4Linux->Stub drivers). You also need
to start Fiasco-UX with ux-con, the graphical console. The lx script
from runux will do that for you when started with the 'con' command.

The problem you are seeing is that Linux doesn't have an active console
and thus fails to start. Enabling the framebuffer will give you a
console and should make your setup work.
