There is no separate SMP kernel in FC6.

It sounds as if the system is coming up, yes?  What does "uname -a" show as

I don't know if your DVD issue is part of this, but this bug has been
reported in multiple bugzilla entries.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=214402

is one of the entries.

Seems to be about right....

What is the output of "lsmod"?  Also, "cdrecord -scanbus".
