Except clearly it's not, because you have etch versions of lvm2,
libdevmapper1.02, and dmsetup installed.

Etch userspace packages are expected to be compatible with the 2.4 kernels
in sarge.  In cases where they aren't this is a bug in etch, not in sarge;
even if someone was inclined to do an ABI-changing, oldstable upload of the
2.4 kernel for a non-security bug, there's no guarantee at all that users
will install that package before attempting an upgrade to etch, so the only
reliable way to deal with the problem is on the etch side.

Steve Langasek                   Give me a lever long enough and a Free OS
Debian Developer                   to set it on, and I can move the world.
