Alternatives are not the correct tool for this. Take a look at the dpkg-divert stuff, divert the original libs, and add a symlink in their place. I think another (likely safer) way to do this would be to create a directory somewhere with symlinks for all libraries you want to replace (pointing to the intel ones), and add it first in the ld.so path. Never did this, though. Anyway, whatever you do, do it in a chroot first. If you get it wrong, you could render the system unusable. -- "One disk to rule them all, One disk to find them.
