Here is a working quik.conf from my PowerBook 2400 (which is 
essentially a repackaged 3400 so it's very similar):

init-code = "dev /bandit/ohare/via-pmu backlight-on"
partition = 3
device = ata0/ata-disk@0
root = /dev/hda3
timeout = 50
image = /boot/vmlinux-2.4.10-pre8-ben0
         label = linux
         alias = l

The init-code line turns the LCD backlight on so you can see the quik 
prompt.  I don't know if it's necessary on the 3400, but on the 2400 
you can't see a thing without it.

Open Firmware variables are set as follows:

boot-device     ata0/ata-disk@0:3
boot-file       linux
boot-command    boot

Some explanation about boot-file: Open Firmware doesn't use this 
variable itself when you boot via quik, because quik is a bootblock 
based loader.  However, it does get used by quik to determine which 
"image" you want to boot by default.  You can either specify a path 
to a kernel, or you can use one of the labels defined in quik.conf as 
I did above.

In this case, Open Firmware failed to find boot-device, and therefore 
couldn't even load quik.

Now OF is actually opening a partition (probably the key thing was 
going from just "ata" to "ata-int"), but the partition opened is not 
bootable.

It turns out that some OF versions (not all!) in PowerMacs specify 
disk and partition numbers in hexadecimal, while others specify them 
in decimal numbers.  I suspect the 2400/3400 use hex.  Try this with 
boot-device set to "ata-int/ata-disk@0:a" or "ata0/ata-disk@0:a".

Here, by telling OF to boot partition 0, you cause it to scan for the 
first bootable partition.  It finds it, but something goes wrong 
after quik loads and tries to load a kernel.  Hopefully if you make 
your quik.conf settings similar to what I have above, it will 
magically start working for you.  :)
