4bpp isn't supported. If you try to use an unsupported number of bpp then X
will try to pick an alternative mode. It looks like X is picking an 8bpp mode
which your monitor can't handle. X currently supports 8bpp and 1bpp. 16bpp
should be supported by the end of October, 24bpp by Christmas and 4bpp by Q3 97
at a rough estimate. I still don't have a good scheme for doing 4bpp colour
mapping so any suggestions are welcome (otherwise you will get greyscale). Note
that X currently *thinks* it can handle 16bpp and 24bpp but in reality it can't
so you may lose your screen display completely if you try to use them.
