It works now.

Good suggestion.  This all gets set up before CAR, so I just had to go
back and find what I'd missed.

alive.diff: Fix a minor spelling error.
emulators.diff: Support qemu and SimNOW K8
pci_read.diff: Add pci_read functions so that the Tyan setup works
tyan.diff: Add support for Tyan s2895 and s2892

All boot tested.
