<pre>OK, so looks like it very successfully creates a GT214_DISP object, and then
proceeds to call nv50_display_create. This then does not trigger *any* further
traces, and errors out. It errors out before the dmac is initialized, and I
think something in the list head thing fails.
Now, as I recall, SPARC has 8k pages. You could try bumping some of those 4096
values up to 8192 and see if that magically makes it work, at least a little
(like the nouveau_bo_new).
If you're sufficiently interested, you could add a lot more prints throughout
that file to see exactly what fails, and then try to resolve it.
It might be an uphill battle though - a bunch of stuff is tied to 4K pages, I
think.</pre>
