Circling back around replying to my own issue in the off chance that someone else ran into this problem and this helps them out. Think it's probably a pretty edge case though not too many folks seem to be running Sun's anymore.
I was able to dump the contents of the NVRAM by booting of an older version of OpenBSD. In my case I went clear back to 5.3 because that was just a CD I had. When I get more time maybe I'll figure out where the functionality breaks and see if I can fix it or at least provide a clear bug report. But for now, once I had the 3 files that ldomctl dump produces I saved them off and loaded 6.2. I was then able to create and load my own ldom config into NVRAM. Happy to say I now have a few T5120's that are running 8 ldoms each. (8x8 cpuxram). Should now get a couple more years life out of these expensive wind tunnels.
