This bug was fixed in the package initramfs-tools - 0.99ubuntu2

---------------
initramfs-tools (0.99ubuntu2) oneiric; urgency=low

  * hook-functions: Revert changes from 0.98.8ubuntu3. With the current
    implementation of copying, and /etc/ld.so.conf now existing in initramfs,
    we can leave libraries at their original location. Thanks to maks for
    pointing out!
  * init: Add back compatibility symlink for /dev/.initramfs, until all
    packages using /dev/.initramfs have been moved to /run/initramfs.
    (LP: #810221)

Title:
  Video output stops on real root after July 12 udev changes

Status in “initramfs-tools” package in Ubuntu:
  Fix Released
Status in “initramfs-tools” source package in Oneiric:
  Fix Released

Bug description:
  In Ubuntu Oneiric, since the July 11/12 udev, initramfs-tools,
  basefiles (/var/run to /run ) changes, plymouth flickers to black,
  causing all video output to cut off ("no signal" report from monitors)
  until /etc/init/plymouth-upstart-bridge.conf runs, restarting video
  output.

  If /etc/init/plymouth-upstart-bridge.conf  is disabled as a test,
  video does not resume at all, showing this to be what is bringing it
  back.

  Booting with splash removed from the grub command line produces
  continuing video output without this flicker, though no script for
  logging output with plymouth produces output during this time (as my
  scripts normally would on console).

  Thus, it seems that either plymouth needs to be patched to adapt to
  the /run changes, or that there is a problem elsewhere concerning
  video devices during this transition.
