Some drivers don't fully support devfs yet.

As explained in MAKEDEV in RELENG_4, /dev/vga is compatibility
cruft for a pccons interface and/or X.  It shouldn't exist, but
still seems to be used by X:

$ strings -a /usr/X11R6/bin/* 2>&1 | grep dev/vga
strings: /usr/X11R6/bin/xterm: Permission denied
/dev/vga

$ grep -lr dev/vga /usr/X11R6 2>&1
