First, I will point out that Google has responded by saying Android is “no more [a fork] than Red Hat Enterprise Linux or any other distribution vendor. All kernels are in some way a fork for some amount of time, the trick is keeping that delta small. We’re trying to do a better job of keeping a small delta.”

Whatever.

But reading this thread, I am confused about the use of the kernel in smartphone OSs. My question is, if I ferret around in the Nexus One's Andriod 2.1 and the N900's Maemo 5 will I find:

a) both Android 2.1 and Maemo 5 contain the Linux Kernel 2.6.33
b) only Maemo 5 contains the Linux Kernel 2.6.33
c) only Android 2.1 contains the Linux Kernel 2.6.33
d) neither Android 2.1 and Maemo 5 contain the Linux Kernel 2.6.33

Pick one.
