These fixes greatly improve qemu booting on PPC - many Linux
distributions with kernel 2.4 now work. It's two big patches (one for
qemu, one for OpenHackWare) - let me know if someone prefers them broken
out into smaller pieces.
There's still some work to be done to get PREP in good shape as well as
a Linux 2.6 kernel to work well - expect some more patches in the near
future.
Highlights
* Real serial
* Correct PCI host bridge for PREP (wrong in Pearpc, Qemu and
OpenHackWare)
* -Werror building for OpenHackWare
* proper reboot
* HFS OpenHackWare now correctly traverses the B*tree - greatly improves
probability of booting *all* HFS based filesystems
* Many, MANY other fixes
