On the Uno (mega328) the pullups are 20K to 50K. The 2560, I don't know off the top of my head, but would think that they would be similar to the 328. The data sheet will tell you.

Edit: page 355

It is same for all ATmegas 20-50k. Reset pin it has little bit higher.

As mentioned, 20-50K.

Why do you ask?
