I've been running 2.5/2.6 kernels every day since 2.5.1 was released :)
Coda works fine, and in some ways better because 2.6 doesn't have the
NFS ESTALE hack in namei that causes validation problems for anyone but
NFS. Those 2.4 problems are sadly enough only really noticable for Coda,
possibly be cause we have an active callback mechanism to purge stale
data out of the kernel, while everyone else either assumes that noone
else can possibly change data without going through the kernel, or uses
some a timeout based method.

The realms patches were merged around 2.6.0-test5, so you don't even
need to patch the tree or build your own kernel-module.
