Hm, I tried to express something different: Is the kernel on the
boot-floppies doing a "detour" over OF to reach the screen or is it just
accessing the graphics-card directly (i suppose the latter one)?
If it would be using the first method, would the debian-installer
appear on the serial-console when I set OF to use it?

I had (luckily) no problems to redirect the OF console to the Mach64,
the output-device is "/bandit/ATY,mach64" as stated on
http://penguinppc.org/projects/quik/defaults.shtml -> quirks.
Nevertheless, thanks for your hints.
Greetings,
