As I understand it this is where the third ioctl argument is used
as data instead of a pointer to data.
This is only useful to provide source compatibility to non-BSD
sources, and there are ways to get that without tainting the
interface at that high level.
Also, there might be problems with 32/64bit compatibility.
Look for the term "gross and disgusting hack" in
sys/dev/wscons/wsdisplay_compat_usl.c.

best regards
Matthias
