I'd been following the randr-1.2 branch for a while, but it broke a while ago
(and is still broken now it's been merged into HEAD). I finally did a
git-bisect and tracked it to this change:

commit cc8e1d95f1b90a259beea4e8cc4d7e29af660919

    RADEON: Major rework of BIOS table parsing

    - greatly simplify ATOM and legacy connector table parsing
    - use bios tables to detect LVDS and TV outputs
    - add support for TV table parsing (legacy only)

Now when I try:

xrandr --output VGA --mode 1920x1200 --right-of LVDS 

It exits with no errors and doesn't turn on the external display.
