stipulations for using the Linux kernel?
I am working on a new open source operating system for games and I would like to be able to use the Linux kernel so that I am not re-inventing the wheel. What are the stipulations for using the Linux kernel? Being that it is strictly for games, what *nix (Unix, Posix, Linux, etc.) standards do I follow, if any? Since it is an OS for games, would I be inclined to follow these standards or, more bluntly, can I do with the kernel as I will? My goal with the gaming OS is to strip out everything in Linux that would not or may not pertain to games or game development and maybe change a thing or two (but NOT in the kernel since the API for game developers will be a separate thing).
Basically: what am I allowed to do with the kernel? what am I required to do? what cannot I do?

The Kernel is also covered by the GNU General Public License. Any changes to the code must be documented and shared with the rest of the community. You can read more about that here.

Note that open source does not mean you cannot sell your stuff. It just means you have to share as well. People will pay for "free" stuff if they feel they are getting value for $$.
What about Pay Per Use? i.e. So that I'm not having to reinvent the wheel, I'm looking at using the Linux Kernel in an OS for arcade games (yes, the kind you put your quarters into). Because I'm not selling the OS (nor intent on making any changes to the Kernel) but rather charging people to play the games that will sit on top of the Kernel, would that violate any license agreements?
