post-lucid I have not encountered this issue, so I think it's probably
resolved now.

Title:
  [script splash] missed passphrase keypress for encrypted HD

Status in “plymouth” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: plymouth

  On the MSI Wind U100 netbook, plymouth_0.8.0~-12  and
  plymouth_0.8.0~-10 both miss some keypresses during LUKS passphrase
  entry. I'm not going to publish the passphrase as it is a high-
  security machine.  The versions of Plymouth that did not give message
  or passphrase prompt output from the initramfs did not have this
  problem on any of my machines. Maybe asking Plymouth to do more is
  slowing it down on slower machines?

  There is no problem whatsoever with my desktop machine (AMD Phenom II
  X4), only the Intel Atom, a slower processor. The problem is not the
  same from boot to boot, and if a particular attempt to boot gives a
  lot of trouble, power cycling for another try is the easiest way to
  boot. Some attempts take every press-and a few even miss the first
  keypress. Passphrase is a long high-security passphrase exceeding the
  passphrase box in length, so the last characters can't be verified.
