Forwarding this bug report from Ubuntu reporter Timo Witte:

[Problem]
On line ~ 964 in the file radeontool.c the framebuffer is mapped via 
"pci_device_map_region(avivo_device, fb_region, 1)" this operation returns a 
EAGAIN (error code 11), which is generated by the libpciaccess. The Frambuffer 
Region is found correctly (in radeontool, avivotool just searched for 128M 
regions). I think this might somehow be a problem with changed kernel acccess 
behavior over time. I ran the tool from an X Session as root, and from remote 
ssh (without X running in the foreground [ctrl + alt + f1])

I don't see what this has to do with the radeon X driver...

I suspect it might have something to do with this though.
