Well, on SVR4, VT1 (/dev/vt01) is not the first VT, but the one activated
with Alt-SysReq F1.  The first one is /dev/vt00, which is activated with
Alt-SysReq H (H for "home" I think).  I think that in XFree86 we tried
to keep the relationship between the VT numbering and the way it is
activated consistent across different OSs.  /dev/vt00 and /dev/console
are the same device on SVR4 (at least by default).
