Comment 12 for bug 606373

This is functional and tested in maverick AMIs with cloud-init 0.5.15-0ubuntu2 (20100916.1 and later).
I decided that I basically had 3 options:
a.) disable plymouth
b.) fix/add support to plymouth to, when configured as such, write data to /dev/console as it would have written to /dev/tty7 (or /dev/XXXX when it sees console=XXXX on the command line).
c.) boot with console=hvc0

The easiest solution was to boot with console=hvc0. If there comes a time when we are forced to merge multiple platforms (ec2 and eucalyptus) into a single pre-generated bootloader configuration file, then we'll cross that bridge then.
b.) boot

cloud-init (0.5.15-0ubuntu2) maverick; urgency=low
  * grub-legacy-ec2: boot with console=hvc0 (LP: #606373)
