[fprint] successful installation on HP-Compaq nc6400

[Alexander Danilov]

Thanks to the author for fprint, it was really long waiting software. I install libfprint and 
pam_fprint on my HP-Compaq nc6400 (Debian etch) with AuthenTec 2501 fingerprint reader.
I can say - it works.
But there are some notes, the patch for old imagemagick was _very_ useful, enroll and verify works,
but need some documentation about how to setup usb device (set right permission) with udev and 
without it, because running enroll using sudo is not a good idea. The second note about pam, i have 
seen pam configuration for version 0.99 at wiki page, but it doesn't work for my case, my pam is 
v0.79. I try to setup pam to use password or fingerprint and check it using ssh to localhost, at the
first ssh ask me for password, and then wait for fingerprint(valid or invalid), and let me to log in 
only if I input right password, not matter of what finger I use for login.

Small wish: it will be good to have some options to turn on debug messages, as a good example I can
recommend to look at pam_usb.
