Hmm, in case the ThinkPad is still in use i wouldn't recommend this. OEM:DM keys are bound to the machine they got activated first.
Good question, never used these MSDM tables to activate a system in VM . Using it for testing Multi OEM Project and such tools.
Assuming @sebus is correct, it should be sufficient to export thr MSDM as BIN with RWEverything on the OEM machine and load it in VMware.
