This sounds like you have kernel configuration issues. Was the ext3 file
system enabled?  In your grub or lilo configuration are you using
root=LABEL= or a more standard definition?  Have you tried compiling and
installing a kernel without SELinux?  If this is a 2.6 kernel, you might
want to get the 2.6 kernel working on the system before dealing with
SELinux.  You might want to look at
http://www.codemonkey.org.uk/docs/post-halloween-2.5.txt for information
about moving from a 2.4 to 2.6 kernel.  If you don't want to compile
your own kernel you might want to look at the kernels available at
http://people.redhat.com/arjanv/2.6/  You also didn't say if you were
using Fedora, Red Hat Linux, or something else as your base.  While that
shouldn't matter for the kernel, it may make a difference later when
trying to get the non-kernel parts of SELinux running correctly.

Other than enabling SELinux in the configuration, compiling an SELinux
kernel should not be very different from compiling any other kernel.
