Yes, I'm running XFree86 on Linux/x86. In the setup program, you can
select which resolutions you'd like to use, and cycle between them with
[CTRL ALT +] and [CTRL ALT -]. A similar thing can be done with bit-depth,
although I'm not up on that because I leave it in 24bpp all the time (I
hate Doom). :)

Yeah, it's true all right. It was written for DOS, in the time of
640x480x8 screen resolutions...you know, waaayyy back in 1993...
