The problem is where to put the serial number, and how to distribute it.
It needs to be maintained in a ,v file for cvs to be able to check it
out. That adds additional complexity.

It's correct enough to give a the "effect latest source" date for
a particular kernel build irrespective of what parts of the tree
are there. It doesn't matter if alpha/ has been committed to more
recently if that source isn't being used in this kernel.
Also, it doesn't take "ages". It takes a little while, but not ages.
