<pre>Aha, I think I know what's going on. You're using AGP, which means you get to
use the ttm_bo_manager_func. This in turn allocates nodes as drm_mm_node, which
is *totally* different from nouveau_mem. (And that's what gets stored in
mem->mm_node.)
Can you change
if (!node->memtype)
/* untiled */
break;
to
if (nv_device(drm->device)->card_type < NV_50 || !node->memtype)
break;
and see if that helps? I actually semi-suspect that this is a giant issue with
the TTM stuff the way we're using it, but perhaps all the other uses are
guarded behind card < NV_50 logic as well, but that's not obvious to me.</pre>
