Ennn, my poor English. I have not set any font from grub.
When I setfont lat1-08, font become smaller,and I can see more
characters on the screen.
But it looks like different from when I set the "just fit" video
parameter to grub.
Then grub parameter way looks more comfortable.

I just not have the "CONFIG_LOGO_xxxx"and "CONFIG_DUMMY_CONSOLE",
but the "vga=xxx" works for my kernel.
I've tried your config file, still not work for me. :-(
Since I does not speed a lot time on a local console, I'll use the
"vga=xxx" for now.
When I'm free I'll go on dig it.
Thanks.
