Well I seem to have got past the AppleACPIPCI issues, but it still shuts down.

The issue seems to be this:

/dev/disk1s4: Can't initialize disk cache

I have tried booting into single user mode and it gives me the same error if I try to run fsck manually.

If I boot into Leopard it can run fsck_hfs -f over that that volume without an error.
