Tested linux 3.0 RC1 to run knoppix. It works, pretty much like any other kernel upgrades. There is nothing which are out of my expectation.

But of course, the usual problem of knoppix on new kernel still applies, ie have to find/modify/compile the aufs and cloop kernel module.

These days the author of aufs have been pretty slow on aufs development. I hope he won't drop his support for aufs one day.
