What we will do is temporarily deactivate the TPM. There's a command for 
that and in the lower-level error paths (that I am funneling through a 
single function now) we will send it to the TPM. The TPM will stay 
deactivated until the next reboot. I think this is a better solution 
than aborting the boot.
