kernel dependency?

[Jim]

i want to remove the latst kernel installed,  cause when i di updates
things got a bit out of hand.   (something to do with a second HD)
so i opened the terminal and did this...

[jim at My_World ~]$ su -
Password:
[root at My_World ~]# rpm -q kernel
kernel-2.6.9-1.667
kernel-2.6.9-1.681_FC3
[root at My_World ~]# rpm -e kernel-2.6.9-1.681_FC3
error: Failed dependencies:
        kernel = 2.6.6-1.435 is needed by (installed)
kernel-ntfs-2.6.6-1.435.i6 86
[root at My_World ~]#

why would such a old kernel still be installed?
