I've not seen this myself.  could you provide a console log
(euca-get-console-output) of the image that is broken?  And exactly what
cirros image you're using? (ie, the disk.img or the uec tarbal...)

I really can't imagine anything that would mess up password based auth
with the cirros user.

Sure, I wouldn't recommend password based auth anyway.  It is only enabled
in the cirros image as its intent is test.  please do not run cirros
images with default password for anything important.
