I imagine it can be done, as (a) it is sort of documented, and (b) X11 does it (but X11 links something into the kernel; what?) If I set the size field of struct kd_memloc to anything larger than 128K I (sometimes) get a memory fault when accessing that memory. I have had little luck setting video modes that require more than 128K, but think I have a pretty good idea of what I am doing as I can get quite a few smaller VGA modes.
