quik boots only manually

[Tobias Stefan Richter]

quik will not autoboot on my PowerMac 4400, when left alone no timeout 
will boot the machine automatically. I have to enter either a kernel 
path or quik label name to start up. Just hitting enter I see this:

   Enter the kernel image name as [device:][partno]/path, where partno is a
   number from 0 to 16.  Instead of /path you can type [mm-nn] to specify a
   range of disk blocks (512B)
   boot:

After entering something reasonable quik loads the specified image 
(specified either by label name or path) just fine. 
Setup looks like this:

        init-message="Debian GNU/Linux PowerPC (woody)"
        default=Linux
        timeout=100
        root=/dev/hda2
        partition=2
        image=/boot/vmlinux-2.4.20-ben10
                label=Linux
                read-only
                append="console=ttyS0,38400"
        image=/boot/vmlinux-2.2.20-pmac
                label=orig
                read-only
                append="console=ttyS0,38400"

Any ideas how to start this machine automatically?
