Which of these machines really require the Cirrus? The xen ones look 
like that they can deal with std. The isapc is should probably stay at 
the Cirrus.

Also the "none" seems to be a false-positive. I suppose they mean 
"empty", i.e., no graphics card at all?

And at least the ppc ones can be canceled out, they should work with 
std, the new default (expect the sam460ex which goes an own route for 
now).

What is the indented target release for the patch?

If the patch is applied to 3.1 then I think there is enough time to fix 
issues caused by the patch. Additionally, a warning could be put in the 
ChangeLog for 3.0 that in 3.1 that the default mode will be std unless 
machines define an own default. This is should be enough time for people 
to complain or to fix things.

If the patch is to be applied to 3.0 then all non-ppc ones need to be 
reconsidered.

The "important" ppc machines have been fixed already. I can do the 
remaining if this is wanted.

Bye
Sebastian
