<antrik> well, in theory, specific kernel drivers can expose their own
device_map() -- but IIRC the only one that does (besides mem of course)
is maptime -- which is not a real driver either...

<braunr> oh btw, i didn't know you had a blog :)
<antrik> well, it would be possible to replace the device interface by
