Your line is correct. The reason for the warning is that your card is
dual-head, and both heads have their own pci address. The message is
harmless as both fglrx and radeon understand the second head without
needing it configured.

In my case:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AS
01:00.1 Display controller: ATI Technologies Inc RV350 AS (Secondary)
Which is why the second controller doesn't show up, apparently it isn't
VGA-compatible :)

Besides the direct rendering, you can also check the opengl version:
$ glxinfo|grep -i opengl
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV350
OpenGL version string: 2.1 Mesa 7.11.1
OpenGL shading language version string: 1.20
