Which AMD/ATI video cards don't require non-free firmware when using the radeon driver?

nouveau has a convenient matrix showing which cards are supported without having to use non-free firmware (card families not tagged as EXTFW). Is there an equivalent table for radeon?

I've looked at radeon's similar feature matrix page but wasn't able to ascertain this information.

According to Debian's AtiHowTo page:

Proprietary, binary-only firmware (aka microcode) was removed from the Debian kernel's radeon DRM driver in linux-2.6 2.6.29-1, to resolve Debian bug 494009.

The firmware can be provided by installing the firmware-amd-graphics or firmware-linux-nonfree package.

Without this package installed, poor 2D/3D performance in the radeon driver is commonly experienced.

Some GPUs may require firmware to operate the X Window System, or do dual display.


Based on the information on the Beyond Linux From Scratch site, it seems that all ATI/AMD GPUs require firmware blobs.
