The new lck patchset against 2.4.25 is available at http://www.plumlocosoft.com/kernel/. It's changed its name to prevent confusion with Con's new 2.6.x ck patchset. FWIW, I'm the maintainer of the lck patchset, if you guys have any issues with it in the future. (I have been keeping any eye on the gentoo bugzilla).
In CVS; should reach Portage soon. I've decided to keep it in ck-sources for now...
