Just update to Fedora 13, Goddard.
Although I manage to install cursor, it seems gnome did not update the default cursor. Therefore, we need to change the config.
You can see several icon there. A new cursor folder should be there. If none, do copy the cursor folder to /usr/share/icons
in this directory, you will see index.theme. Default is dmz-aa. Change to cursor folder name you want to. In my case, Comix.
Restart X. (logout and login)
For Comix cursor, you can get it here.
