Can you boot into single user mode?

What do you mean when you say that you tar'd up /etc and put it into /etc?

Does /opt exist on it's own partition, or does it live on the /
filesystem?

You set diag_switch? to true or false only. It is diag_level that you set
to "max". That wouldnt be likely to help with your problem, though, as
that only presents low-level POST hardware checks and isnt relevant to the
OS.
