hi,
   I installed on VM using command:

$ sudo qemu-system-ppc -M mac99 -cpu G4 -m 
1G -cdrom /mnt/sda2/debian-13.0.0-powerpc-NETINST-1.iso -boot 
d -hda /mnt/sda2/deb-solo-ppc.img -vga std -monitor stdio -net 
nic,model=e1000 -net tap,ifname=tap0

then I add packages and dependencies: lxdm, lightdm and fluxbox lxde-core

but when restart I view in dmesg:
