Well, my previous installation gots broken so I'm following another
way because I don't have any machine to build a custom PPC kernel
(avoiding cross-compilers).
I got the images from:
ftp://ftp.suse.com/pub/suse/ppc/update/BETA/kernel/power3/
exactly: zImage.chrp-power3-2.4.16-SMP-3
This image can boot on console without problems.
My way on your comments:

On a DHCP server:
host power3 {
filename "/tftpboot/zImage.chrp-power3-2.4.16-SMP-3";
next-server nfs_server_IP;
option root-path "/tftpboot/myIP";
hardware ethernet 00:11:22:33:44:55;
fixed-address my.fixed.ip;
}

In my case, I booted from NFS. So:
My /etc/exports looks like:
/tftpboot myIP(rw,no_root_squash)
The same root.bin were used:
http://ftp.debian.org/debian/dists/woody/main/disks-powerpc/current/chrp/images-1.44/root.bin
but in a different way, too.
$ mv root.bin root.bin.gz
$ gunzip root.bin.gz
$ mount -t ext2 -o loop root.bin /tftpboot/tmp
$ cp -ax /tftpboot/tmp /tftpboot/myIP
$ umount /tftpboot/tmp
So, now it's ready to boot by network.
In OpenFirmware:
boot net root=/dev/nfs nfsaddrs=myIP:nfs_server_ip
root-path=/tftpboot/myIP nfsroot=nfs_server_ip:/tftpboot/myIP
console=ttyS0,9600

Well, now it's complaining about "root fs", but I'll repartition
