FIXME!! Some objects we need to access from userspace are created in kernel. Only the ..V0_NEW ioctl on kernel objects appears to be freely usable from userspace at this point, and also accessing objects that are created from userspace in the first place. The channel object is created in kernel in nouveau_chan.c, I suppose.
