Indeed. I had a few nightmares getting it going efficiently (a 1bit screen
is not ideal, a 4bit screen does not have enough colours, and some
programs do not like 5bit screens) until I started using the X server
in 4bit greyscale mode, i.e. my .xserverrc looks like this;

exec X -width 700 -height 535 -depth 4 -X 4 -Y -10 -emulatemiddle -cc GreyScale 

This way all programs get the "colours" they need as all 16 grey shades
are fixed at startup. Not as good as proper colour, but better than
monochrome. YMMV.
