This development version of LVM2 requires a 2.6 kernel - it relies
on patches added to 2.6 upstream about a year ago.

Either upgrade to a 2.6 kernel or downgrade your lvm2 & device-mapper 
packages.

It would be straightforward to backport the changes to 2.4 but
nobody's done it yet.  Patches welcome!
