Emmanuel, from the upstream bug: For kms, agpmode is a kernel module parameter. try booting with radeon.agpmode=X where X = -1,1,2,4,8 1-8 are the agp modes, -1 uses the onboard gpu gart (PCI, PCIE, etc.)
Please give that a try. Also, dont' forget to subscribe to the upstream bug report and give comment there.
