With Alex, Dinar's and Ben's help I figured out that the type=06
partition is the culprit here. The YaST partitioner sets it up correctly
as type=41, but when ext4 or btrfs is used, it gets converted from PReP
to FAT16.

Selecting ext3 in the partitioner leads to an error during bootloader
installation when it tries to shrink the PReP boot partition using:

/usr/sbin/parted -s /dev/sda resize 1 2048s 2191s

parted does not recognize the filesystem in /dev/sda1 (there is none in
such a PReP boot partition) and therefore refuses to resize it. I used
fdisk to manually delete and recreate it using these start and end
sectors and ran
dd if=/media/cdrom/suseboot/yaboot.ibm of=/dev/sda1

That made the disk bootable for SMS and OF but yaboot does not find its
config. Creating an ext3 primary partition 3 in the space between
resized PReP boot partition and extended partition and placing files
/etc/yaboot.conf and /etc/yaboot,cnf did not help. (I still have to try
/yaboot.cnf.) The following worked to boot into the installation:

yaboot: disk:6,/boot/vmlinux initrd=disk:6,/boot/initrd

There are still some errors though, like DHCP4 hanging (although it does
in the installer) and something localfs-dependent network hangs, too.
Using static IP, default route and static nameserver worked. Shutting
down the system has the same problems as starting up and this is
reproducible on every boot. All feels a bit unstable but that might be
just the current state of Factory.

Unfortunately osc is not available yet, to work on improving things from
the ppc machine.
