radeonEnsureEmitSize() in radeon_tcl.c is called from radeon_run_tcl_render().
radeonEnsureEmitSize() walks through the pending state to make sure it will all
fit in the current command buffer, but it appears to be missing some additional
state that's being emitted.  If you run the game from the terminal, it should
print out a warning:
   if (emit_end < rmesa->radeon.cmdbuf.cs->cdw)
      WARN_ONCE("Rendering was %d commands larger than predicted size."
          " We might overflow  command buffer.\n", rmesa->radeon.cmdbuf.cs->cdw
- emit_end);


Most likely:
radeonEmitArrays()
radeonEmitEltPrimitive()
radeonEmitPrimitive()
is emitting more state than radeonEnsureEmitSize() thinks it should.
