Actually I was thinking of note 1;  Evergreen and later chipsets all
require WITH_NEW_XORG, and are supported only since version 10 kernel
which implies having significantly different code.

I'm guessing, initially, there will be some cutoff between older/newer
cards, older cards having the regression you described, and newer cards
falling back in the convenient way I describe, with the potential to
get KMS working easily.

I may try to find/borrow various models of Radeon card to test.
