pam broken in sid

["Michael B. Taylor" <mtaylor@vorticity.engr.utk.edu>]

As others have stated, the -26 version of pam in sid is broken, so if you 
install it, you wont be able to login at all.

Unfortunately, I *have* installed it and don't have a session open.
Question:  What is the best way (using a rescue disk) to 
fix/circumvent/whatever pam well enough to be able to login once and repair 
the situation with the new debs?

Thanks,

Mike
