Seems like you could specify it in your xorg.conf:
http://www.x.org/archive/X11R6.8.0/doc/xorg.conf.5.html#sect12  (Scroll
down just a bit to the "Visual" directive.)  Of course, this assumes
you've already got this section in your xorg.conf, which may not be
true, as many distributions make use of the X server's much-improved
autodetection nowadays.  You'd also need to set the (color) Depth to 8,
apparently.

Judging from http://www.x.org/archive/X11R6.8.0/doc/Xserver.1.html
(linked from the other page), you may be able to do something like
"startx -- -render gray" (if I recall the syntax correctly) when your
display manager (xdm, gdm, kdm) isn't running, or "startx -- -render
gray :1" if it is.
