thx google translate :-)

you need to ad one line to the fb driver im kernel.

edit this in your kernel ../linux/drivers/video/fbmem.c

Rewriting point (fbmem.c, near line 1050)

   case FBIOPUT_VSCREENINFO:
        return 0;       #### INSERT THIS LINE ####
        if(copy_from_user(&var...))
        return -EFAULT;

recompile your kernel(uImage) and be happy.

took me half a day to fix this litte problem. :-(
