Something like:

cd /usr/src/
diff -rNu linux-2.4.21pre4aa1 linux-2.4.21pre4aa2 > patch

should do it.

install Tim Waugh's patchutils [1] and do an

  interdiff -z 2.4.21pre4aa1.gz 2.4.21pre4aa2.gz > my-aa1-aa2

Make two trees, one with aa1, one with aa2. Diff them. (The "slow, painful"
method.)

You could also use interdiff from diffutils.

Ok, works great.

But the patches created by interdiff and the method proposed by Joshua
are different :)
5kb of differences. Intriguing.

look for a package called patchutils, which includes interdiff. 

mulix@alhambra:~$ apt-cache show patchutils
Package: patchutils
[snipped]
Description: Utilities to work with patches
 This package includes the following utilities:
  - combinediff creates a cumulative patch from two incremental patches
  - dehtmldiff extracts a diff from an HTML page
  - filterdiff extracts or excludes diffs from a diff file
  - fixcvsdiff fixes diff files created by CVS that "patch" mis-interprets
  - flipdiff exchanges the order of two patches
  - grepdiff shows which files are modified by a patch matching a regex
  - interdiff shows differences between two unified diff files
  - lsdiff shows which files are modified by a patch
  - recountdiff recomputes counts and offsets in unified context diffs
  - rediff fixes offsets and counts of a hand-edited diff
  - splitdiff separates out incremental patches
  - unwrapdiff demangles patches that have been word-wrapped
