-virtual kernel missing modules

The -virtual kernel is missing several modules that were present in the -virtual kernel in oneric.

Simple instructions:
 * include aufs.ko
 * include overlayfs.ko (just noticed that we'd like to have this)
 * include veth.ko
 * veth.ko (CONFIG_VETH): i need this

Read on for more information

$ find /lib/modules/3.2.0-4-virtual |
  sed '/.ko$/!d; s,.*/,,' | sort > 3.2.0-4-virtual.list
$ find /lib/modules/3.0.0-13-virtual |
  sed '/.ko$/!d; s,.*/,,' | sort > 3.0.0-13-virtual.list

## here is the list of modules that were present in oneiric but
## are not in precise
$ cat 3.2.0-4-virtual.list 3.2.0-4-virtual.list 3.0.0-13-virtual.list |
  sort | uniq -u
ahci.ko
aufs.ko
blowfish.ko
ghes.ko
hed.ko
veth.ko
xen-platform-pci.ko

## here is the list of modules that are *new* in the precise package
$ cat 3.0.0-13-virtual.list 3.0.0-13-virtual.list 3.2.0-4-virtual.list |
  sort | uniq -u
6lowpan.ko
blowfish_common.ko
blowfish_generic.ko
blowfish-x86_64.ko
can-gw.ko
cordic.ko
crc8.ko
crypto_user.ko
de2104x.ko
de4x5.ko
dm-bufio.ko
dmfe.ko
dm-persistent-data.ko
dm-thin-pool.ko
igbvf.ko
ip_set_hash_netiface.ko
ixgbevf.ko
pptp.ko
sha1-ssse3.ko
twofish-x86_64-3way.ko
uli526x.ko
winbond-840.ko
xen-kbdfront.ko
xen-netback.ko
xen-pciback.ko
xircom_cb.ko

Now, 1 by 1 of the ones we lost:
 * ahci.ko (CONFIG_SATA_AHCI went from 'm' to 'y'), I'll assume this was by
   design
 * aufs.ko (CONFIG_AUFS_FS), this seems to have just gotten lost, it is built
   as module in both kernels.
 * blowfish.ko (CONFIG_CRYPTO_BLOWFISH): seems that this is handled by the added blowfish_common
 * ghes.ko (CONFIG_ACPI_APEI_GHES): went from module to builtin
 * hed.ko (CONFIG_ACPI_HED): went from module to builtin
 * veth.ko (CONFIG_VETH): i need this
 * xen-platform-pci.ko: seems this is handled by xen-pciback and such.
