Ok I understand.

FWIW, based on my trials:

    * DirectFB support on BE hosts is somehow easier than with
      carminefb: the patches from Nikita Egorov are working almost out
      of the box (they basically change every single access to memory so
      that it becomes ABGR, so that a simple memcpy to/from Carmine
      memory is already the right alignment. I don't know if it would be
      working without these patches on kernel >2.6.26 (with
      FOREIGN_ENDIAN defines) since I'm currently stuck to a vanilla
      2.6.24.6
    * However, DirectFB has some troubles with panning, which is working
      using a different approach by myself: I'll check it and see if
      it's worth posting here.
    * 800x600 resolution is supported if I try 800x600-24@60  before
      trying 640x480-16@60

Thank you,

What about the mb86290 framebuffer driver directly from Fujitsu which is
in the mainline kernel?
    

This mb86290 framebuffer driver from Fujitsu isn't in mainline, it
is in the DENX Linux Kernel tree.

It's from 2003 and supports only until 86293, but can it be used as a
basis for a proper fb driver? It has a lot of features indeed...
    

I think it won't be accepted in mainline. It was developed for 2.4
Kernel and slightly modified for 2.6. These features could be added
to the new driver which is intended to provide initial support for
Fujitsu GDCs in mainline now.
