Hi all, thanks for your suggestions.

It's solved. The trick was to upgrade from xen 3.0.2 and kernel 2.6.16.26 to xen 3.0.4 and linux 2.6.16.33

I briefly had a problem getting it going even with the new bits, but that turned out to be for unrelated reasons (bad /lib/modules).

The recipe in a nutshell:
  Install xen 3.0.4 from source tarball as per the README.
  Compile kernel for built-in (not modular) dm-mod, loop, and ramfs.
  Don't use the mkinitrd command line shown in the README.  Instead, use the so-called "second easiest way" or making initrd, as described in the Gentoo Root-LVM howto.  The generic mkinitrd only installs modules, it doesn't know how to start LVM volume groups.

Derek.
