Fedora Hardware :: No 3D Acceleration Support Using Mesa Drivers

I've been struggling with getting my graphics card configured under a fresh install of F13. I have an ATI Radeon HD 5450 1GB DDR3 and when I run glxinfo this is the result:

Code:
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:
GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, ....

What concerns me are the lines:
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer

If I try to enable Desktop Effects it tells me I have no 3D acceleration. So 3D acceleration not supported for this card using the open source, stock install drivers? I'd like to avoid the proprietary ATI ones if I can. Background on the video card here: [URL]. It's the cheap-o model in the HD 5XXX series and based on the article above it seems to be more of a beefed up version of the HD 4XXX chip design than a true HD5XXX series card.
