FC5 dri problems

    Have there been any reports of the agpgart speed of the radeon
drivers being downgraded for certain cards? Today, because of breakage
in the current fglrx livna package, we reverted our machine with a
ATI FireGL 8700/8800 QH (AGP) back to the stock radeon driver. This
provided excellent 3D performance when we first installed FC5. Now
even though DRI is initialized the glxgears speed is down near 400 fps.
I believe I have identified the cause of this. Where the fglrx drivers
result in...

to appear in the messages file. Is this a known regression and is there
a why to force the radeon driver back up to 4x AGP?
