Transforms should work.  Rotation, which uses transforms, works fine.  This
might be a bug in exa or the xserver.  With the following patch:

--- a/src/r600_exa.c
+++ b/src/r600_exa.c
@@ -1231,6 +1231,8 @@ static Bool R600PrepareComposite(int op, PicturePtr
     shader_config_t vs_conf, ps_conf;
     struct r600_accel_object src_obj, mask_obj, dst_obj;

+    return FALSE;
     if (pDst->drawable.bitsPerPixel < 8 || pSrc->drawable.bitsPerPixel < 8)
        return FALSE;

All transforms will be done by software.  I get the same results with hardware
or software.  Unfortunately, I don't have an intel system to compare with.
