   That ifdef could just be DRM_IOCTL_MMAP

I guess so, but it's only on NetBSD that mmap actually doesn't work
and you have to use DRM_IOCTL_MMAP.  It's also sleazy enough that I
made us define our own ioctl; I don't want to tempt fate by pretending
it's a general non-NetBSD API (yet).

           struct  drm_mmap  map_req = { 0 }; works just fine?

In this case it does, but I got in the habit of the above pattern
because `= { 0 }' doesn't work if the first member in the structure
type is not an integer or pointer.  Would be nice if `= {}' worked,
but it's not standard.
