Actually the Coda module in the standard 2.4 kernels doesn't support
realms. The introduction of realms broke non-Coda users of the Coda
kernel module, so for stability reasons it hadn't been updated. Also 2.4
went into a bugfix/maintenance only cycle for a while. I'm not sure if
they reopened it for backported 2.6 features.

I guess by now anyone who wants to use our kernel module probably knows
how to deal with realms if they want their code to work with 2.6, so
except for cleaning up the patch and getting it ready in small
manageable chunks there isn't a real reason not to push the realm
related updates to Marcello for inclusion in a future 2.4 release.
