I just installed 7.0 on a 2.6.x kernel without problems.
Some file permission problems, ok. Easy way around: install as root, then 'chmod -R a+w' the lv-directory (all users can write. If you don't like this, you might as well create a group which is allowed to write) and run as user.
Example finder works fine, so does the rest (except some methods as report printing etc.)
(btw, install openG- really useful! www.openg.org! Jim Kring rules!)
