I wasn't aware of Ralph's packages. Thanks for the pointer.

I'm installing Xen by doing:

        mkdir /usr/local/src/xen
        cd /usr/local/src/xen/
        wget http://bits.xensource.com/Xen/latest/xen-3.0.1-install-x86_32.tgz
        tar -pzxf xen-3.0.1-install-x86_32.tgz
        cd xen-3.0.1-install
        apt-get update
        apt-get install bridge-utils
        apt-get install iproute
        apt-get install python2.3
        apt-get install python
        sh ./install.sh
        update-rc.d xend defaults
        update-rc.d xendomains defaults
        mv /lib/tls /lib/tls.disabled

Then I (attempt) to set up a new entry in /boot/grub/menu.lst, which  
is where this conversation started.

From the comments at the top of /usr/sbin/mkinitrd:

        $Id: mkinitrd,v 1.201 2004/05/16 22:00:48 herbert Exp $

It does look for both dm-mod and lvm-mod. I'm happy to email the  
mkinitrd script if anyone would like to take a look.
Cheers,

Mark.
