I've been searching the Internet and have not had any luck.

I work at a school and we have iMacs that need to restart after the user logs off so it can get back to the dual-boot screen.

Is there a way to either remove the logout button or tie the restart functionality to the logout button?

Hmm. Can you provide more details on exactly what you want to do? Why do you need to reboot the machines? And why don't you ask the users to restart instead of just logging off? If you're managing a bunch of machines, maybe net booting and Mac OS X Server would be the best way to go. I haven't used it, but I'm sure others will chime in.

From the description, I think he has shared iMacs that must return to the boot selector after each person uses it. So the next person can choose between OS X and Linux.

Looks like Login Logout Tasks would do what you want. Just add an applescript to reboot.

Or you can just use a LogoutHook which is probably what Login Logout Tasks is doing.

I thought the user had to hold down the option key to get to the dual boot screen, no?

There are ways of getting it to come up. There are also OS X utilities that load at boot and present a boot selector that reboot to the desired OS.

If you can't use (or don't want to trust) logout hooks for this, then your best option depends on how you have your system setup:

1) If you have an auto-login set, then your best option is probably going to be to create a LaunchAgent that reboots the system and set the LimitLoadToSessionType key to an array with the only item being the string "LoginWindow". This will mean that every time the loginwindow would appear it will instead reboot. There may be consequences for this, so this is definitely not all environments.

2) If you have people loggin in with their own credentials, then you either use #1, but have a flag file that gets placed the first time it runs (and then looks for this flag file for the second instance), or you have to rely on a logout hook or a daemon process that starts when the user logs in, and reboots when it gets the quit signal (the latter being more work, but very reliable).

Oh, this is probably not the best forum for this sort of question. Better forums would be afp548.com's forum, or the MacEnterprise mailing list. Apple also has some lists, but they are not quite as good.
