AIUI you have to list the files explicitly.

Not that I know of; I just redirected the output from 'find', as on
http://pigeon.dyndns.org/stuff/lvm-root/lvm-root.html.

I'm using woody, and the woody version of mkinitrd doesn't have that
error message... I downloaded the sarge/sid version from
packages.debian.org and had a (quick) look at the script ('mkinitrd'
is a shell script), and from that quick look it does look like a bug;
it seems to check if the modules exist and if they don't it assumes
the kernel doesn't support LVM, without checking whether the support
has actually been compiled in.
