Maybe you're looking for this:

Right. I didn't mention that earlier for two reasons:
  1. the allowed numbers (e.g., 792) seemed like pure magic, with no
explanation of how the numbers are calculated or their precise meaning;
  2. as you say, it is deprecated, so I didn't want to rely on something that
might go away.

However, since it seemed to work for you, I tried it (with "794") and it works
fine. In particular, opening :0 and :1 works properly, unlike the case when I
used the GRUB_GFXMODE option. The console text is still quite a bit larger
than it was when using nouveau, but it's acceptable. So I now consider the
problem solved. Thank you very much for your patience.
