yaird should work with 2.6.8 and newer.

Alternatively kernel-package could fallback to other (installed) tools
if the default one fails, instead of hardcoding version numbers. Still
the priority of tools looked for and attempted would make sense to
adapt to the kernel version, but would then be less intrusivese.
mkinitrd could then have hardcoded that 2.6.13 and newer Will Fail(tm).
yaird by design is quite knowledgable at build time about the chances of
an image being broken (because it probes hardware at build time, where
mkinitramfs probes at runtime) and will fail if something is wrong.
Don't know avbout mkinitramfs but at least situations like "needs 2.6.12
or newer" could be hardcoded if it would otherwise silently build a
broken image.

If I understand you correctly then that only helps users frewuently
bringing their system up-to-date, and not someone doing a dist-upgrade
a year from now...
