Yes, I just don't want to support R/W mappings, so I let it crash. :)
See bug #704083 for a refresh on that. It's hard to achieve read/write mappings
with HW buffers, unless you actually use userptr underneath for very particular
use cases.

Besides, this is an interesting way to realize that HW accelerated elements did
not get auto-plugged in.
