Just put it into vc_screenbuf after register_framebuffer() returns, and
force redraw...
 

Or Maybe simply tell vc_resize that we use a special way of reading the framebuffer.

Or i should implement the trick you use for setting the card in 
graphic mode later on in the setvar stuff ?

If you'll override save_screen, and you'll put set_origin() into visual_init,
I believe that it will work:

(1) in take_over_console, copy data to screenbuf using your own save_screen.
(2) now vc_resize (with prior set_origin) will copy data from old screenbuf
    to reallocated screenbuf (instead of from videoram to reallocated
    screenbuf).
(3) and update_screen() will just paint data which are already on screen
    if resolution changed. If resolutions matched, it will put data on the
    screen.

mmm, will try.

BTW, how can i force a redraw from pm3fb ?

If you'll override save_screen, and you'll put set_origin() into visual_init,

NO, just tried, i got no more display, and the box hanged ...

How i do it :

i copy the data in pm3fb just after i first map the framebuffer. i hold it in a special
array in pm3fb (for now).

But then, maybe i should see if the location of the set_origin should be changed, maybe i could do it in vc_resize for now.

BTW, in the first case, i will see the screen flashing shortly with the garbage i see now, and then work ok, isn't it ? And i would need to handle resolution changes myself ?

Friendly,
