Sorry, forgot to add that notice carries this important bit of information:

====
ATTENTION: Due to an unavoidable ABI change the Ubuntu 6.06 and Ubuntu
6.10 kernel updates have been given a new version number, which
requires you to recompile and reinstall all third party kernel modules
you might have installed. If you use linux-restricted-modules, you
have to update that package as well to get modules which work with the
new kernel version. Unless you manually uninstalled the standard
kernel metapackages (linux-386, linux-powerpc, linux-amd64-generic), a
standard system upgrade will automatically perform this as well.
====

So, if for example you have compiled a VMware Server Console kernel for
instance, VMware *won't* work with linux-image-2.6.15-28-386 (Dapper) or
linux-image-2.6.17-11-386 (Edgy) unless you recompile the VMware kernel
again. At least that was my experience on Dapper 6.0.61.
