Indeed, and the version of the metapackages doesn't include an explicit
reference to the ABI. IMO it should, then we could do:
Depends: linux-image-2.6-686 (>= 2.6.21-1), linux-image-2.6-686 (<< 2.6.21-2)

Currently you have to lookup the changelog of linux-image-2.6-686 to know
the ABI it corresponds to, which is somehow inconvenient.

BTW, the version numbers in the changelog doesn't correspond to the
version numbers of the generated package. While this is allowed, its there
a compelling reason to do so in this case?

$ zless /usr/share/doc/linux-image-2.6-686/changelog.gz
linux-latest-2.6 (7) unstable; urgency=low

  * Update to 2.6.21-1.
  * Remove etch transition packages.
