I'd rather just let existing users hang out to dry. First off there aren't 
really 
any existing users. Anyone who is or might be a user of the new code is 
probably following these threads closely. Second the xen tpm driver 
hasn't even been accepted into linux yet so there really is not any 
"official" version 1.

I can update the documentation to state the requirements on the new
tpm driver version in the current linux tree so that nobody tries to use the 
old version in the
xen 2.6.18 tree.
