Created attachment 144442
  --> https://bugs.freedesktop.org/attachment.cgi?id=144442&action=edit
quickfix, working with 19.x mesa versions (tested: latest)

Added a proposed quickfix based on "possible fix" from Marek.

This version now works with latest mesa and I suspect it does not break
anything else with other cards neither. Still could be cleaned up a bit by
finding and changing which r300 code paths ask for VRAM and GTT domains
together and changing code there, but this works so far.

This change favors VRAM domain over GTT domain when both are provided. For more
available memory, you can change it the other way around easily, but this seems
to favor faster speed over more memory available.
