Bug#515866: MacBook Pro keyboard unresponsive at LUKS prompt with kernels >= 2.6.27

[Matt Kraai <kraai@ftbfs.org>]

Package: initramfs-tools
Version: 0.92o

When I boot a 2.6.27 or later kernel on my MacBook Pro and try to
enter my passphrase at the LUKS prompt, nothing happens.  This appears
to be

 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/310460

The attached script, when put in /etc/initramfs-tools/hooks, includes
the hid-apple module in the initrd if it's available, which fixes the
problem.

It would be helpful to have something like this included in the
standard initramfs-tools package.  I have a couple questions about how
it should behave, though:

 * Should it only include the module if LUKS is in use?
 * Should it only include the module if the module is needed for
    * this computer model (i.e., a MacBook Pro)
    * any of the attached keyboards (what about keyboards that are
      attached later?)
   ?
 * What about other the hid-* modules?
