Well, it definately shows up now on console.
I have tried using -current as of 060606 and also
3.0.
It boots up to a point where the login prompt should kick in, but then 
pukes.

Here is the console output.

The ascii junk is what shows up when it hits this point, and when I try to

The system also stops responding to ping at the sametime...
