The main Lift trunk (including all binaries available from scala -tools.org) will not work on Scala 2.8 due to breaking changes.
However ... There are two branches: 280_dev and 280_port are available on github (at http://github.com/dpp/liftweb ), if you are ready to compile it yourself.
Because projects cannot even be guaranteed binary compatibility between successful nightly builds of Scala 2.8. You will be advised to wait at least until the beta version 2.8 is released, as I believe that the elevator will also issue the corresponding binary at this time.
UPDATE
Climb 2.1 supports Scala 2.8.
