However, I learnt pfb (PCI Frame buffer) had disappeared.  Did you
delete arch/bebox/pc/pfb.c and arch/bebox/pci/pfbvar.h at the time of
merging ppc-oearenovation?  Or, did you move?

Did it ever exist? Somehow I doubt it since I can't think of a generic way to deal with a PCI framebuffer without firmware help. For instance, which BAR maps the framebuffer? Or, if you want to use it as generic VGA you still need firmware help to enable it, nowhere near all PCI graphics chips power up in VGA mode. If the BeBox firmware sets up a graphics mode of some sort and you can get parameters like video memory address, width, height, stride and depth you can simply use genfb.

have fun
