The interesting part of the kernel log contains:
[ 12.178607] No connectors reported connected with modes
[ 12.178614] [drm] Cannot find any crtc or sizes - going 1024x768

It looks like nouveau is failing to find any acceptable modes. Since this is a laptop, that probably means that it's unable to find an LVDS mode, either in the VBIOS, by ACPI, or via EDID.

Upstream will probably want a vbios dump - you can get that with “sudo cat /sys/kernel/debug/dri/0/vbios.rom > ~/vbios.rom”

It would also be nice to get dmesg a boot with drm.debug=0xe, to have the most possible useful debugging info.

Once we've got those things this should be sent upstream.

I think the vesafb thing is not a part of the problem, although upstream will probably complain about it :(.
