Just one from when you have the problem is less confusing!
Looks hunky dory to me, so likely it's between the firmware and kickstart. You could check early-boot Boards menu or run Sysinfo/SysSpeed and check the memlist.
That's what I can suggest, I don't know enough about ACA1230 but from this
it's clear to me that you won't get any ACA1230 RAM unless you MapROM kick 3.1, you're using 2.05.
