The thread followed here on GS was that you did indeed need to create an
area 0 interface to bring up the VL to begin with. You COULD then remove
that area 0 interface, and the VL would still stay up (which seems more a
bug than a workaround).
In getting to that point (as I found the whole thing mildly amusing), I had
done tests on multiple platforms with multiple IOS versions and always found
the same results. Without that initial interface to bring it up, it ain't
gonna happen.
BUT.... Your final configs may not show that interface there. Go figure.

Funny you mentioned this, check this thread:

I'd love to know what magic is being performed to get this to come up
according to IE. I have configured my lab about as close as possible to
their rack setup, from a hardware and IOS standpoint and I can't make it
work.
One person comments that they were able to get it to come up with 12.2T
based code, only my BB's are running 12.2T and I have no plans on
downgrading R1-R6 just to see if I can make this work.
