i think the # of people realistically using <=2.4 nowadays is beyond carrying about, especially wrt downloading & building recent software. mainstream projects (like glibc) have been requiring linux-2.6 for years now. so if dropping this code provides a nice clean up, and you're merely requiring linux-2.6, then i say go for it. -mike
