One final data point which is likely to be of interest to those here: I have 
an Intel "Tunnel Mountain" reference board designed specifically for UEFI 
testing, which has a Tianocore reference firmware implementation on it based 
on UDK2010. That firmware does _not_ exhibit the same bricking problem as the 
AMI-based cases: it seems to detect and delete the invalid boot variables at 
start-up, which duplicates the OVMF behavior.
