I'm not that familiar with dmabuf, but are you saying it's not possible
for a kernel driver to request the buffers? They _must_ come from the
userspace?

Anyway, even if it would be possible, if the tiler is a part of omapdrm
we need omapdrm to get and use the tiler buffers. And we can't have
omapdrm running when using omapfb, because they both use omapdss.
