Oops, I only just noticed that my kernel (3.13.2) is rejecting CS buffers:

[  377.460557] radeon 0000:01:00.0: r600_cs_track_check:756 mask 0x00000777 |
0x00000FFF no cb for 2
[  377.460563] radeon 0000:01:00.0: r600_packet3_check:1708 invalid cmd stream
[  377.460566] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

This is with libdrm 2.4.52 and Mesa f47e5.
