Hi Rhonda!
Where you at the debconf8? You've a powerbook if you're the Rhonda of
the debconf :).  I don't know if you remember we had a few beers
togethere with Jacob, Antoine and Anne, I'm Sébastien from Montréal.

  I've a powerbook (aluminium) and I experimented a similar problem with
an external DVI monitor. VGA monitor works fine.  I resolved it using
radeontool. There is a referrence
maybe it leads you to a solution...  I can't find the documentation that
I used to solve the issue.

have a nice day,
