I can't reproduce this on ROCK Linux with bash 2.05a:

[tsa@azathoth ~]$ echo $SHELL
/bin/bash
[tsa@azathoth ~]$ /bin/bash --version
GNU bash, version 2.05a.0(1)-release (i686-pc-linux-gnu)
Copyright 2001 Free Software Foundation, Inc.
[tsa@azathoth ~]$ ls "!x123456"
bash: !x123456: event not found
[tsa@azathoth ~]$
