Yes, exactly, this is the same as I saw at one point.

From Bryce's build log:
  CC radeon_exa.o
In file included from ../../src/radeon_exa.c:547:
../../src/radeon_exa_funcs.c: In function 'RADEONDownloadFromScreenCS':
../../src/radeon_exa_funcs.c:557: warning: implicit declaration of function 'radeon_bo_is_busy'

"radeon_bo_is_busy" appeared in libdrm 2009-08-22 but the driver was built with libdrm-radeon1 2.4.12+git20090801.45078630-0ubuntu1

I thought the symbol list magic would prevent this, but maybe we haven't got that right. Or upstream need to flag a dependency. For now, please try the libdrm packages from the xorg-edgers PPA.
