Radeon DRM issues and filling up /var/log with gigabytes of logging

I'm running FC11 with:

xorg-x11-server-Xorg-1.6.4-0.1.fc11.x86_64
xorg-x11-drv-ati-6.12.2-14.fc11.x86_64
kernel-2.6.30.9-92.fc11.x86_64

etc.

The hardware is an Asus M3A78-CM motherboard with onboard video.

I'm seeing the following filling up my /var partition in 
/var/log/Xorg.0.log:

(EE) RADEON(0): RADEONCPGetBuffer: CP GetBuffer -22
(EE) RADEON(0): GetBuffer timed out, resetting engine...
(EE) RADEON(0): RADEONCPGetBuffer: CP reset -22
(EE) RADEON(0): RADEONCPGetBuffer: CP start -22
(EE) RADEON(0): RADEONCPGetBuffer: CP GetBuffer -22
(EE) RADEON(0): GetBuffer timed out, resetting engine...
(EE) RADEON(0): RADEONCPGetBuffer: CP reset -22
(EE) RADEON(0): RADEONCPGetBuffer: CP start -22


and in /var/log/messages:

I wasn't getting these when I was running FC10, which supposedly came 
with an earlier version of xorg-x11-drv-*... or possibly the kernel (and 
the DRM modules).

This is rendering the machine largely unusable, because rpmbuild, mock, 
sendmail, etc. all need large amounts of space on /var.

My config file is below.

Anyone know what the remedy to this issue is?

Thanks,
