Emacs doesn't number the undos. It keeps up to a certain amount of bytes in 
a buffer, regardless of the number of undos. In other words it keeps, say, 
30,000 bytes, whether that's one undo or 2,000.

There is an undo group in your Options > Customize Emacs menu. It gives you 
two limits. Just put in larger numbers. I put extra in mine because I have 
lots of RAM. You might have to experiment a bit to get a good number for 
the way you work.
