After discussing this with Colin Watson in #ubuntu-devel I've found a work around that is more agreeable.
Create '/usr/share/grub-gfxpayload-lists/blicklist/11_virtualbox' with the following content:
v80eedbeef.*
Run the following to update the blacklist and grub.
sudo update-grub-gfxpayload sudo update-grub
The boot process will now be text only for Virtualbox guests and the default X resolution is 1024x768.
The other benefit of this approach is that if full disk encryption is used, you are now always able to enter your pass phrase. So this technique is also a fix for https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1386005
