Yes. IIRC vga16fb uses a planar format instead of packed pixels so it
would not work with DirectFB even if we had DSPF_LUT4.
Actually... A quick look at the vga16fb code indicates it does support
4bpp and 8bpp packed modes too. So DirectFB could work if a 8bpp mode is
selected, ie. having pixelformat=DSPF_RGB332 or pixelformat=DSPF_LUT8 in
your directfbrc. Unfortunately vga16fb does have a video memory limit of
16KB in these modes...
