I spoke too soon. Please wait I post a new version for testers. I will 
email this list.
Then try:

db = DAL('google:sql://[app-name]:[db-name]/[table-name]')
...
auth.settings.extra_fields['auth_user'] = [Field('username_fb', length=128, 
default="", unique=True, writable=False, readable=False)]
auth.define_tables(username=False, signature=False)

consider that migrate_enabled is true by default so no need to set it. Also 
the check_reserved keywords is designed for SQL and not GAE. It does not 
hurt but it is not necessary. I do not swear by lazy_table because they 
have some caveats. Let's try without that.

Can you help us check if this work? If, not what behaviour do you see? Do 
you get a traceback?
