Forwarding this bug report from Ubuntu reporter Timo Witte:

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])
