Hi Fajar, I'm trying to access an encrypted HDD on the dom0, not in a
domU. In fact, I don't have any domU's setup on that server yet. So,
how will this work for dom0 then? I have honestly never compiled a
custom XEN kernel before, and the last time I even compiled any
kernels was on FreeBSD 4.6 & RedHat 4 - a long time ago.

Ok, but what will happen when I run yum update? Can / will it
overwrite the custom kernel, or will it give me errors?

It's a CentOS 5.2 which has been updated with yum upgrade recently.
But, running yum update kernel last night gave me this kernel
