sorry, can not confirm this.

if nothing helps, there is always the "rescue" system on you
installation cds ...
or, if your boot loader permits this:
boot with init=/bin/bash :-)

SuSE 8.1, kernel.org 2.4.22, no special pam settings.

larsjohann$ grep root /etc/passwd
root:x:0:0:root:/root:/bin/false
(0) 16:08:32 ~
larsjohann$ su
Password:

-- /bin/false drops me back to my "lars" prompt

(0) 16:08:42 ~
larsjohann$ su -s /bin/bash
Password:
(0) 16:08:51 /home/lars
rootjohann#

-- ok, now I'm root again, hack away ...
