No, that isn't correct at all.

For servers you always have to patch the kernel, because we have not
yet gotten the required features/exports into the kernel, and it is
unlikely that this will happen in the near future.

For clients, you can build and run against unpatched upstream kernel.org
kernels 2.6.16-2.6.22.  Support for kernel API changes in 2.6.23 and later
is still in progress.
