I don't think there's any particular problem with qemu-system-ppc per
se; it's more the _firmware_ we use in it, which is a quick hack which
was just about sufficient to get older kernels (and AIX etc.) working.
These days, it isn't really sufficient. New kernels expect a sane and
complete device-tree, etc.

At some point in my Copious Spare Time™ I mean to try to fix it, or
maybe even port the version of OpenFirmware that we're using on OLPC.
Spare time hasn't exactly been copious recently though :)
