Did you cd into the directory before mounting it? If so, then your
shell will actually be in the old directory (which presumably has
permissions that won't allow that) and you need to cd again :

b at amidala:~$ cd /mnt
b at amidala:/mnt$ ls -ld .
drwxr-xr-x  3 root root 72 Mar 30 15:01 .
b at amidala:/mnt$ mkdir this
mkdir: cannot create directory `this': Permission denied
b at amidala:/mnt$ ls -ld /space
drwsrwsr-x  2 b b 48 Nov 24  2004 /space
b at amidala:/mnt$ sudo mount --bind /space /mnt
b at amidala:/mnt$ ls -ld .
drwxr-xr-x  3 root root 72 Mar 30 15:01 .
b at amidala:/mnt$ ls -ld /mnt
drwsrwsr-x  2 b b 48 Nov 24  2004 /mnt
b at amidala:/mnt$ mkdir this
mkdir: cannot create directory `this': Permission denied
b at amidala:/mnt$ cd /mnt
b at amidala:/mnt$ mkdir this
b at amidala:/mnt$ cd /

Otherwise, I'm baffled for the time being...
