Just in case anyone else searches and follows up the discussion in regards to a bootlogo not working, the following steps must be completed in order for them to show...
1. The actual jailbreak MUST have been applied with the "enable bootlogo" option enabled, otherwise no matter what you do or install afterwards, bootlogos won't work. If you forgot to do this, you can easily run redsn0w over the top of your current setup as long as you ONLY select the "enable bootlogo" option.
2. "Animate" must be installed from Cydia.
3. BootLogo in the "Settings" app on the iPad must be configured and a bootlogo selected.
Note, the bootlogos that come with the "Animate" package are designed for the iPhone and look terrible on the iPad - Try downloading "Aninmate Apple' which is a nice full screen iPad bootlogo to test.
Finally, of course, REBOOT!
