New images for amiga and atari are here:
http://people.debian.org/~cts/debian-m68k/linux-image/
All other arches had SERIAL_CONSOLE already enabled, it seems.

user-startup calls autoboot (it seems I do not need any 060 commands or
libraries, at least on kullervo).
;--- schnipp ---
;c:setpatch
;c:cpu060
EXECUTE s:autoboot
;--- schnapp ---
autoboot looks like this:
;--- schnipp ---
IF exists SYS:linux/boot-2.6.24-1
ECHO "Booting kernel 2.6.24-1"
WAIT 10
DELETE SYS:linux/boot-2.6.24-1
EXECUTE SYS:linux/Linuxstart-2.6.24-1
ELSE
ECHO "no kernel 2.6.24-1"
ENDIF
IF exists SYS:linux/boot-2.6.22
ECHO "Booting kernel 2.6.22"
WAIT 10
DELETE SYS:linux/boot-2.6.22
EXECUTE SYS:linux/Linuxstart-2.6.22
ELSE
ECHO "no kernel 2.6.22"
ENDIF

linux/Linuxstart-2.6.24-1 is created by a script, looks like this:
;--- schnipp ---
sys:bin/amiboot-5.6 -k sys:linux/vmlinux-2.6.24-1-amiga root=/dev/sdb4
video=amifb debug-mem
;--- schnapp ---
to /etc/crontab I added this
;--- schnipp ---
@reboot root /usr/local/sbin/select-kernelversion boot
;--- schnapp ---
select-kernelversion is this script (which is slightly different on crest
and kullervo for the ADOS and ROOT variables)
;--- schnipp ---
#! /bin/bash
# select kernelversion
# install: copy uncompressed vmlinux to Amiga DOS partition, create boot
# script
# boot: create AmigaOS file to select default boot kernel
#VER=2.6.18-4
VER=2.6.24-1
ARCH=amiga
ADOS=/dev/sda1
ROOT=/dev/sdb4
echo "kernel version vmlinux-$VER-$ARCH"
case "$1" in
install)
if [ -e "/boot/vmlinuz-$VER-$ARCH" ]; then
mount $ADOS /mnt
gunzip -cd /boot/vmlinuz-$VER-$ARCH > /mnt/linux/vmlinux-$VER-$ARCH
echo \
"sys:bin/amiboot-5.6 -k sys:linux/vmlinux-$VER-$ARCH root=$ROOT
video=amifb debug-mem" > /mnt/linux/Linuxstart-$VER
echo "yes"> /mnt/linux/boot-$VER
ls -l /mnt/linux/
umount /mnt
fi
;;
boot)
if [ -e "/boot/vmlinuz-$VER-$ARCH" ]; then
mount $ADOS /mnt
echo "yes"> /mnt/linux/boot-$VER
ls -l /mnt/linux/
umount /mnt
fi
;;
*)
echo "Usage: select-kernelversion {install|boot}"
exit 1
;;
esac
exit 0
;--- schnapp ---
When a new kernel is installed, the script should be called with the install
option, after VER has been updated. This kernel needs to be added (manually)
to the top of the autoboot script, so it will be tried first. If that kernel
fails to boot, on the next reboot, an older version will be tried, until one
boots. If the new kernel failed, on the next reboot it will be activated
again for autoboot, so this needs to be fixed manually as well. So a few
things could be made better, but it has been working fine so far and there
are several fallback kernels on the machine.

Since I need to reinstall, it can not hurt. But you guessed where the real
problem is...
