Simon, would you be willing to work with me and test some things?  I
suspect, from the names of your modules, that you're running on a Mac,
and we may just need to add that one module (mac_hid) to the list.

Title:
  keyboard doesn't work to enter password with panda and encrypted
  partitions

Status in “initramfs-tools” package in Ubuntu:
  Confirmed
Status in “initramfs-tools” source package in Precise:
  Fix Committed

Bug description:
  This ended up being two bugs, one is for missing modules in the
  initramfs-tools static list (which is true for all arches), and one is
  that ARM specifically seems to be getting a wonky initrd.  The precise
  SRU is targetting only the former issue, so lts-quantal kernels (which
  don't build on ARM) can have USB keyboards still functional in their
  initrds.

  [IMPACT]
  Users with certain USB keyboards and no USB->PS/2 BIOS emulation will no longer have keyboard control in their initrds after upgrading to an lts-quantal kernel.

  [TEST CASE]
  If you have the affected hardware, re-run update-initramfs -u both with and without the updated initramfs-tools (with a quantal kernel installed on precise), reboot with "break=bottom" on the command line, and see if you have a keyboard.

  If you don't have the affected hardware, do the above initrd
  generation, and compare results, the new one should include hid-
  logitech-dj and hid-generic.

  [Regression Potential]
  Next to none.  initrds may get a tiny bit larger, but not by any meaningful amount.

  [Original description]
  Installing quantal server on panda from the 20121013 image, a normal install with guided partitioning works fine, and keyboard works during and post-install.

  However, if I select lvm+encrypted partitions from the partitioning
  screen, after rebooting the keyboard does not work for entering the
  password to unlock the disk, which prevents booting the system.
