On mine, I just put Linux here, not the path to the kernel.
Then the quik.conf Linux label controls the boot.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I don't know what this is doing in here?

quik doesn't grok symlinks, you must have copied your kernel there?

Things to try:
* append="video=atyfb:vmode:5"
* append="video=ofonly"
* don't append anything
(append="video=ofonly" is what the standard boot floppy uses).
Remember you always have to run quik after changing the quik.conf
According to http://docs.info.apple.com/article.html?artnum=112401
your machine supports several modes, you might want to try some
of the other vmode numbers as well.
