This is a known issue and has been fixed in an NMU. Take a look at
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=258839>. You can
safely ignore these messages. What is happening is dosfsck accesses a
word/long word on an unaligned boundary. This causes kernel to trap this
access and emulate the unaligned access. dosfsck gets the data it wants
but kernel complains about it. If the message bothers you, you can
update to version 2.11-2.1.
