Comment 5 for bug 659084

@Haakon,
I just did, on x86_64 (I assume i386 is the same):

# install the -server package
sudo apt-get install linux-server

# on x86_64 there is a '-server' kernel, on i386, it is '-generic-pae'
flav="server"
[ "$(uname -m)" = "x86_64" ] || flav="generic-pae"
sver=$(uname -r)
sver=${sver%-*} # remove '-virtual', sver will be like '2.6.35-22'

sdir=/lib/modules/${sver}-${flav}
tdir=/lib/modules/${sver}-virtual
module="nfs"

# parse modules.dep to get which modules $module depends on
mods=$(sed -n -e "\|/${module}.ko:|"'!'"d" -e 's,:,,p' "${sdir}/modules.dep")

for m in ${nfsmods}; do
   [ -f "${tdir}/${m}" ] && { echo "${m} already existed"; continue; }
   echo "${m} -> ${tdir}/${m%/*}"
   sudo mkdir -p "${tdir}/${m%/*}"

   sudo cp -a "${sdir}/${m}" "${tdir}/${m}"
done

sudo depmod -a

sudo modprobe nfs
