Hi Rex:

This has no effect.  Leaving the password blank and clicking "Unlock" just 
gives a password failed message, rather than falling through to pam_fprint

Here is the /etc/pam.d/system-auth-ac file that works with gdm but not 
kscreensaver:

I haven't had a chance to change my default session manager from gdm to kdm 
yet, so I don't know if this one works.  I'll try it soon and let you know.

On the ubuntu side, where kscreensaver works with fprint here are the 
requisite files:

/etc/pam.d/kscreensaver:
# /etc/pam.d/kscreensaver - specify the PAM behaviour of kscreensaver
#
@include common-auth
@include common-account
@include common-password
@include common-session

/etc/pam.d/common-auth:
auth    sufficient    pam_fprint.so
auth    requisite       pam_unix.so nullok_secure
auth    optional        pam_smbpass.so migrate
