cvsroot :ext:<user>@linux-fbdev.cvs.sourceforge.net:/cvsroot/linux-fbdev
module FBdev/utlilities/fbtest

For testing, I added the following `null' video mode to /etc/fb.modes:

    mode "null"
	geometry 1 1 1 1 0
	timings 0 0 0 0 0 0 0
    endmode

After that, you can try 16 bpp using

    fbset null -xres 320 -yres 240 -depth 16

thanks to the fbdev rule that says modes should be rounded up if they
don't match.

BTW, last week I looked a bit more into xorg. There seem to be some
serious bugs w.r.t. proper fbdev handling (that is, for the exotic case of
something different than 8/16/32 bpp packed pixels). I fixed a few of them,
but it still crashed. Needs some more investigation...
