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 ?
