Description of problem:

If you change GRUB prompt to replace init with the shell
(almost standard rescue procedure when everything fails)

plymouthd blocks keyboard output - no chars (or only something) is shown
in the prompt.

Anyway, is still accepts input, so if you are able to kill plymouthd and reset terminal, it works again.

Version-Release number of selected component (if applicable):

rawhide, plymouth-0.6.0-0.2008.10.30.4.fc10.i386
(encrypted PV, if it has some impact)

How reproducible:
- remove "rhgb quiet" from GRUB parameters and replace with init=/bin/bash
- try to write something when bash shell appears. press enter.

Expected results:
Working rescue shell only. Note that I do not want boot into single user, I need run shell here instead of init (imagine init is broken, udev is broken, etc)
