I have retrieved atom aux/realemu and I will have to test.
But before, I will have to read the aux/vga sources to understand what
it expects. Because aux/vga -p gives me all the informations about the
vesa supported modes of the card, and even the monitor settings (I
wonder that the problem is here, that is monitor and card "discuss" and
the software is not part of the discussion). The informations (vesa: the
RADEON card; edid: the monitor 1600x900):

To be continued:
1) How to fill vgadb.
2) What to pass to aux/vga to not be in 640x480x8 because termrc fails to
this default.
