neostat is a simple command line utility that determines the current state of your neomagic based graphics adapter:

[root@isis /root]# neostat 
neomagic state: $Id: neostat.c,v 1.1 2000/01/06 02:26:44 root Exp $

neomagic: CRT enabled
neomagic is unlocked
[root@isis /root]# echo $?

[root@isis /root]# neostat 
neomagic state: $Id: neostat.c,v 1.1 2000/01/06 02:26:44 root Exp $

[root@isis /root]# neostat

neomagic: LCD and CRT enabled

[root@isis /root]# echo $?

[root@isis /root]#

I use it with cpp to pre-process by XF86Config file so that my laptop can do the right thing (tm) when the Xserver starts.
