You have been subscribed to a public bug:

It is fairly standard practice to include kernel modules in images for
Amazon EC2, but the most recent Karmic AMIs do not include them:

  ami-a40fefcd
  canonical-alphas-us/karmic-i386-alpha5.1.manifest.xml

  ami-a20fefcb
  canonical-alphas-us/karmic-x86_64-alpha5.1.manifest.xml099720109477

Some other options have been discussed like building kernel modules into
the kernel or copying them from initrd into /lib/modules at boot time,
but the easiest approach to get things working in the short term is
probably just to follow the existing de facto standard and include the
kernel modules for the AMI's default kernel.  If somebody wants to run
it with a different kernel, they are already used to having to install
those kernel modules themselves.

Ideally, the addition of the kernel modules would be done by default in
the vmbuilder EC2 plugin so that it works when normal users create
images with vmbuilder.  If it is done some other way, the method should
be documented publicly so that users can create working images.
