EC2 Kernel without rpcsec_gss_krb5 mod

I'm looking into setting up NFSv4 with kerberos (via this). I believe I have everything working except I'm running kernel 3.0.0-16-virtual which doesn't seem to include rpcsec_gss_krb5. Which causes this command modprobe rpcsec_gss_krb5 to fail with FATAL: Module rpcsec_gss_krb5 not found..

If I try to proceed mounting the NFS without this module.

# sudo mount -t nfs4 -o sec=krb5 *my ip*:/ /mnt

Stdout:

mount.nfs4: an incorrect mount option was specified

syslog

gss_create: Pseudoflavor 390003 not found!

RPC: Couldn't create auth handle (flavor 390003)

How should I ago about adding this mod to the EC2 Ubuntu kernel?

If you are running 10.10 (Oneiric) you should have access to the linux-image-extra package which contains all of the modules normally stripped from the primary -virtual kernel. With this installed the -virtual kernel should have all of the same modules as a traditional -server kernel.
