Hi Stéphane

Currently the driver cannot get the supported modes from the display
and thus tries to
set a default mode which your display cannot handle.

We have patches to fix this problem but they haven't landed yet.

In the meantime you can play with the kernel boot parameter video.
video=800x600-32 might work for you.
