This is because the driver sets a fixed range of resolutions possible for
randr. Unfortunately, the max height it sets is actually lower than your screen
resolution... see line 2753, radeon_driver.c. You could increase this to 1200
instead of 1152 and it should work. I think not even specifying a VirtualSize
in the config file would help.
That said, I'm afraid the attempt to get acceptable randr behaviour with the
driver is doomed to fail if the driver can't actually resize the front buffer.
It'll chew up vram, tiling gets disabled etc., because the max front buffer
size needs to be preallocated if you want to connect another display later on.
