Mmm, i did manage to override the vga save_screen function, and copy the good values into vc_sceenbuf, but to no avail. What frustrates me is that i cannot find any reference to some piece of code using the data in vc_sceenbuf to write to the screen again. How exactly does the upper layer restore the screen ?
