Debian lenny works, no problems.
I use a NFS root configuration to test endianess issues
(qemu x86 on qemu ppc on x86 host):

ppc-softmmu/qemu-system-ppc \
    -L ~/src/qemu/savannah/qemu/pc-bios \
    -kernel /tftpboot/powerpc/boot/vmlinux-2.6.26-2-powerpc \
    -initrd /tftpboot/powerpc/boot/initrd.img-2.6.26-2-powerpc.nfs \
    -append \
    "debug root=/dev/nfs rw ip=::::xxx::dhcp
nfsroot=10.0.2.2:/tftpboot/powerpc /tftpboot/powerpc nohz=off" \
    -m 512 --net nic,model=ne2k_pci --net user,hostname=powerpc \
    -hdb /media/vm/qemu/powerpc-swap.qcow2 -boot n \
    --redir tcp:10022::22 --redir tcp:10080::80
