At boot time, on i386, "video=vesa" is passed to the kernel to start the
framebuffer device /dev/fb0 via vesafb driver (built into the kernel).
Later in the boot process, the vga16fb module is loaded, and a second
framebuffer device, /dev/fb1 is created, but sometimes, why i don't
know, the fb devices minor numbers end up swapped.
By default DirectFB accesses the first available fb device (/dev/fb0)
and as 4 bit modes provided by vga16 are not supported, it fails
initializing.
The attached patch takes care of adding to DirectFB configuration file
(/etc/directfbrc) a line indicating what fb device has to be used (the
one provided by vesafb).
A miniiso [1] including this patch is available for testing.
