You're in text mode ??  That shouldn't be when bpp == 4.

Ah.. wrong framebuffer.  That is VGAFB.  Try doing :

   export FRAMEBUFFER=/dev/fb1

before running XF68_FBDev.

Does fbset work ?  Something like :

   fbset -fb /dev/fb1 -g 640 400 640 400 1
or
   fbset -fb /dev/fb1 -g 640 400 640 400 8
or
   fbset -fb /dev/fb1 -g 320 200 320 400 8
   
should change modes and XF68_FBDev should be able to use it.  Though
XF68_FBDev that I recompiled here still doesn't work properly.  On 8 bit
modes it doesn't set the palette properly, and on 1 bit modes it a)
assumes LSBFirst (god knows why), and b) black & white are reversed (and
-flipPixels doesn't work :-<).

Cheers,
