You don't lose the console, it just doesn't start graphics
automatically.  What you could do is have a script fire up the
graphics for you from /etc/inittab or one of the rc scripts.  What
you lose this way is the ability to have people login as different
id's.

In IRIX 4.0, the graphics login will come up even when the console
is set to 'd' (assuming the graphics is present and working).

For now, if the machine is on the net, you could have the person
who wants to use the graphics console rlogin, and then type
	/etc/gl/restartgl
which will start the window system as though they had just logged in.
An rsh command to do the same thing should also work.
