yes, more or less. The option I one tested (and it pretty much works)
is to simply use an older kernel (from the LTS release) for your
client image.  You can pin the kernel package by putting this in

  Package: linux-generic linux-headers-generic linux-image-generic
  Pin: version  3.2*
  Pin-Priority: 1001

Install the older kernel using the regular apt tools and do:
ltsp-update-kernels. Don't forget update the client image too
(ltsp-update-image), since the kernel modules (in /lib/modules) will
be needed for hardware support (kept me searching for hours why the
sound card wouldn't work).
Also, remove any kernel version from your thin client image that is
newer than 3.2.

12.4 is an lts release and will continue to receive security upgrades
for a couple of years to come.

In case you are running 12.4, it is simple: install the generic-pae
edition of the linux kernel package.

P.S. in case you think it is a braindead idea of Ubuntu to provide a
complete thin client solution and disregard pretty much every thin
client cpu out there without PAE support: I share your opinion.
