I've been trying to solve the same problem for several weeks now. I
have a beige G3 with a Rage Pro video chip, using a self-built kernel
2.6.8.1, there's

With this configuration and a command line of

...I needed to set a serial console or it wouldn't boot. Once it had
booted, however, I got the usual virtual consoles and everything
worked fine.
Today I discovered that, if I explicitly set tty1 as a console in
the command line:
> root=/dev/hda1 ro video=atyfb:vmode:14,cmode:32,mclk:63 console=tty1
then everything works as expected, and I get the usual messages on
the screen while it boots.
How does the kernel usually know what to use for a console if it's
not defined on the command line?
