This is expected behaviour on some T400 screens, where GRUB is garbled
or doesn't have a display at all, but GNU/Linux works just fine. You
can use an EHCI debug dongle for text mode serial console in GRUB if
you have that. This issue will probably be fixed after the release,
since it's only considered a minor annoyance and not a blocker for

I don't think this has anything to do with libreboot, since we
hardcode-enable it. I checked and the patch should still have been
applied when building this snapshot. On the front of the laptop on the
left side, near the touchpad, there is a small on/off switch for the
wifi which might have been set to off accidentally. Otherwise, "sudo
rfkill list" can help you determine what the problem is.
