I know I'm ok with this strategy, since time is short in the
1.1 cycle. We can always open a bugzilla item to track this,
just to be sure it isn't forgotten. Preferably we'll get a
qemuppc with a framebuffer in 1.x timeframe and we won't need
this at all. Coming up with something generic and the amount
of testing required doesn't fit the timeframe that we currently
have for 1.1.

But in the end, this is up to Richard, this is just my 2 cents
worth.
