They also get it if they enable FRAMEBUFFER_CONSOLE (which most people
do, right?). I don't understand why we want multiple fonts compiled-in
at all, but ok, that's not up to me.

I don't. I use get_default_font() in the new drm_log.c patches.
Anyhow, I'm fine with 8x16, I just thought people might want to select
other fonts. But I guess it's up to them to deal with that, as long as
I use get_default_font() I guess I don't care.

Feel free to drop this patch then.

Thanks
