LVM2 doesn't require any changes to the disks.  It will understand the
LVM1 metadata.  You don't need to patch your 2.4 kernel to use
device-mapper in 2.6, either.  They can both peacefully coexist, as
long as your boot scripts run the right version of the tools.  A
somewhat ugly solution is to run both version, since only one of them
will do anything anyway.
